[Bug 1361906] Re: gvfsd-ftp crashed with SIGABRT in g_mutex_unlock_slowpath()

 

Hello Wade, or anyone else affected,

Accepted gvfs into utopic-proposed. The package will build now and be
available at http://launchpad.net/ubuntu/+source/gvfs/1.20.2-1ubuntu3 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [ Description ]

  gvfsd-ftp sometimes attempts to unlock an already unlocked mutex,
  which is fatal with glib in utopic and later.

  [ QA ]

  1. Open gedit
  2. File -> Open
  3. Ctrl-l
  4. Type ftp://ftp.gnome.org/
  5. Press enter

  At this point gvfsd-ftp may crash, and you'll see an apport popup if
  so. The operation won't work.

  With the fix it should not crash and you should see the listings of
  the remote server.

  [ Development fix ]
