Hello,

I ran into this on my laptop which has an ATI chipset.  More to the
point, it has a:

Radeon X600, M24 chipset.
Kubutu 10.4 32-bit

I compiled Hugin with the debug version of the wxWidgets libraries and a
few extra dialogs popped up (specific to wx) before it crashes.  These
pop ups complained about certain members being NULL which seems in line
with what has been mentioned in this thread.  This seems to trigger when
a sizer is added to a either the m_GLPreview or the m_GLOverview in
GLPreviewFrame.cpp near line 414.

I had previously been ignoring the other messages that were in the
console, specifically:

Xlib: extension "GLX" missing on display ":0.0"

As this seemed to be GL related I started checking things out and found
that I had nvidia libraires on my laptop even though I didn't have an
nvidia chipset.  Checking the xorg.log in /var/log I could see
references to loading these nvidia libraries.  I also found that
"glxgears" would also crash.  So, I  worked through removing them (sudo
apt-get remove --purge nvidia*) and then re-installed the open source
ATI driver (https://help.ubuntu.com/community/RadeonDriver).  I then
restarted the X server and checked to see that I did not have any more
references to the nvidia libraries in xorg.log.

I was then able to run glxgears without issue.  More importantly, I was
also able to start and run Hugin without issue.

In my case, it seems hugin died with a broken GLX install.  Perhaps
something can be checked in Hugin and a proper error message displayed
however my GL coding experience non existent.

To others experiencing this issue, check and see if "glxgears" also
dies.  If so, check your xorg.log file in /var/log and see if Nvidia
libraries are also being used.

Hope this helps!

- Gerry

Title:
  hugin seg faults at launch

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  I'm running Fedora12-i686.  Attempts to launch hugin (either the version included with F12 (2009.2) or the version in the bugbear repo (2009.4) result in an immediate segfault.  If I delete ~/.hugin, then it runs giving me the 'Top of the day' popup, and as soon as I click 'Close' it segfaults.  The only output that I see when running hugin is:
  $ hugin
  MainFrame::RestoreLayoutOnNextResize()
  Segmentation fault
