FS1: crash when leaving mission 2

[fatty]

Hello Mailinglist!

I think I've found a bug in FreeSpace1. Everytime I leave mission 2 of 
the standard campaign with the jump device FreeSpace crashes and I'm 
back on xterm with the following error message:

-----------
$ ./freespace.bin.testing -w -g
Warning: (src/parse/parselo.cpp:339): (1):
Warning: Error opening externalization file! File likely does not exist 
or could not be found
*** glibc detected *** double free or corruption (!prev): 0x08c8f380 ***
Abgebrochen

Maybe the following backtrace with gdb gives you a hint, what went wrong:

I have compiled my binaries from latest cvs and I'm using the German 
version of FreeSpace1, which was bundled with a gaming magazine some 
years ago.

If you need more information, please let me know.
