Hi Gianfranco, sorry. Again I didn't see your comments. I only get email
when other people post here.

I attached another .psd file but I forgot I had included another smaller
one on the blender thread. Either way both can be used to test.

Regarding the steps, there is one mistake. Blender is very confusing.
When you open file on the main menu, it will only show .blend files (it
will only open those). To see image files you need to use the image tab.

STEPS:

1-Open blender
2-change the main, bigger window that has a cube and camera to the image viewer. To do so, click on the lowest left button of that window (by default the view will be made of many windows, the lowest one is a timeline, I'm talking about the biggest one). The button should have a little cube on it, like the one present on the biggest window. Change it to "UV/Image Editor".
3-That window should change, including the menu where the button is located. Use THAT new menu to open and browse for the PSD file (be careful that if it's not patched every .psd you view will be erased).
4-While browsing, change to thumbnail mode (using the top buttons on that window). That's optional, OR
4b- Open a .psd with that window.

If you can actually see the .psd file, the bug is fixed. If it's black
or you can't see the file, it's zeroed and destroyed, you need to use
another .psd to test again.


On my computer,  Ubuntu 18.04.2 LTS bionic, with the new patched blender, the problem is fixed. The PSD is not destroyed.

Let me know if this helps.

Title:
  [SRU] blender: erases photoshop files

Status in blender package in Ubuntu:
  Fix Released

  Fix Committed
Status in blender source package in Cosmic:
  Fix Released
Status in blender source package in Disco:

Status in blender source package in Eoan:

Bug description:
  [Warning]
  * Since this bug is about a data loss, BE CAREFUL in your testing!
  [Impact]

  When simply accessing a folder that contains a Photoshop file, at
  least in thumbnail mode, as well as trying to open the file for
  viewing or using it as a texture, Blender turn the file in a ZERO kB
  file, essentially deleting it.  This can affect directly users who
  haven't been keeping their original file on the working folder with
  the catastrophic scenario where they'll lose the original file.

  The proposed fix should be backported to Ubuntu 18.04, 18.10 and 19.04
  as all of them are affected by this dangerous issue.

  This bug is caused by a Debian-specific patch.

  [Test Case]

   * Open Blender
   * Go to file browser (maybe change it to thumbnails)
   * Access a folder that contains a photoshop file
   * All photoshop files on that folder will be zeroed out and
     it's unrecoverable, nor there is any message.

  [Regression Potential]

  No regression should manifest as a result for this change.

  I posted this on the main ubuntu bug tracker but I have an impression they will tell me it's ubuntu mate's problem... so here is a copy of the bug at https://bugs.launchpad.net/ubuntu/+source/blender/+bug/1822196

  This was posted on Blender bug https://developer.blender.org/T63045
  It was determined that it doesn't happen with the official downloadable release, only with the one installed through the Ubuntu. Here is the report as filed:

  System Information
  Operating system: Ubuntu mate, both 18.10 and 18.04.2 64 bits, Ryzen 7 2700x
  Graphics card: Radeon fury nano

  Blender Version: 2.79.b+dfsg0-1 from distro

  Short description of error
  When I simply access a folder that contains a photoshop file in thumbnail mode, as well as trying to open the file for viewing or using it as a texture, Blender turn the file in a ZERO kb file, essentially deleting it. Luckily I haven't been keeping my original file on the working folder but at one point this will be catastrophic and I'll lose an original file.

  Exact steps for others to reproduce the error
  Simply open Blender, go to file browser, change it to thumbnails, and access a folder on systems like mine that contains a photoshop file. This doesn't seem to happen on windows. All photoshop files on that folder will be zeroed out and it's unrecoverable, nor there is any message.

  I have tested this on many photoshop files (not intentionally, I
  always just forget that there's this huge bug and to make sure any
  folder I'm viewing doesn't have a photoshop file). All of them became
  zero kb and I had to find the source to recover.

  I'm not sure why I haven't seen people complaining about it but this
  is pretty major.
