I'll add the backtrace later (I'm currently running Windoze)
Thanks for the help! And thanks that I can run FS2_Open under Linux now!

EDIT:
I forgot: I've already tried -novbo
And now the "Backtrace"...
When I start fs2_open, the first thing I get is
(gdb) run
Starting program: /home/maniac/.fs2_open/fs2_open_d
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.

Program received signal SIG32, Real-time event 32.
0xb7e14353 in ?? ()
When I'm continuing and I try to select a animated-glowmapped ship like the Pegasus or any shivan ship I only get:
(gdb) continue
Continuing.
ASSERTION FAILED: "cfbp->data != NULL" at cfile/cfile.cpp:1182

The program no longer exists
And here are the last few lines from the fs2_open.log:
