Description
To repro:
Play some videos in mythgallery. This may have nothing to do with mythgallery but I only see the seg fault here.

fwiw, I think the relevant areas of code have changed significantly since this ticket was created and I'd be surprised if this crash is still reproducible. The segmentation fault occurs in the VideoOutputXv? destructor and references the OpenGL libs (probably while closing the X display) - all references to OpenGL were removed from the VideoOutputXv? some time ago and all X display connections are now handled by MythXDisplay (which should be safer).

Hi, I am using mythubuntu with a reported SVN version of:
2009-11-11 22:39:48.381 mythfrontend version: branches/release-0-22-fixes [22594] www.mythtv.org
and I am getting this problem now. As above it is not specifically mentioned which version this was fixed? Am I still behind and not up to date with the changes mentioned?
My stacktrace (totally reproducible):

Can you get (and attach--please don't paste into a comment) a full backtrace with debug symbols as described in the TicketHowTo and http://www.mythtv.org/wiki/Debugging .
comment:6 Changed 14 years ago by
Yes I can do that. Eeeh, but how do you do it on a mythbuntu distro?
Do I get a SVN build at the same level and do a manual build or...? I have no problems doing that but if there is a mythbuntu way that would of course be preferable.
comment:7 Changed 14 years ago by
I tried building the same version from SVN, without LD_LIBRARY_PATH set I get a segmentation fault but symbols are limited as it then picks up the mythbuntu build. With LD_LIBRARY_PATH set to use everything from the SVN build I cannot get it to core dump. I could not find that there is any way to get a mythbuntu debug build so I think I can't resolve this or get any closer to determine what the problem is, unless you have any ideas? Let me know if you want to see the trace from the run with the mixed build...
