Well, this doesn't affect the gameplay, but maybe it is a bug. I made a backtrace with gdb:

The message I normally get is:

Sorry to add another comment, but I realize I write the wrong svn revision, actually it's rev 5974, sorry for the mistake.

Can you try the patch #1626363 (tracker -> patches), please?

I applied that patch, using the rev 6057 and still get segfault on exit.
I made a again backtrace, and it seems different, here it is:

#0 0x00002b2664d8286d in getenv () from /lib/libc.so.6
#1 0x00002b2663bfe64d in _fini () from /usr/lib/libGL.so.1

This segfault definitely needs to get rid out one day. I will try to make new patch for this. :-)

Last time I played this, I did not get a segfault on exit.

Is this bug fixed?

It is not fixed. This bug is hard to catch because it appears only in few situations, not always. I suspect you can hit this with low memory.

I get simular results but only from ufoai-2.1-source tarball not from svn 7277.
system FC5 86_64 with nvidia geforce 6150 driver version 1.0-8776
2gb system ram 256mb video ram
had to patch src/ports/linux/gl_glx.c per forum topic " "Post subject: ref_glx.so: undefined symbol: XF86VidModeQueryVersion"
this resulted in same message at game exit

did gdb backtrace as follows

this should be fixed due to renderer merge
