Crash in dialog_file_access.c (was Re: Trouble compiling)

[Sebastian Held]

Finally I got my suse box to compile trunk, and voila:
trunk (rev18013) crashes even on linux,  but not the first time you open save 
as...
Here is how to reproduce the crash:
- trigger save as
- press cancel
- trigger save as again -> crashes

I'm currently recompiling trunk with debuging symbols enabled to get a 
meaningful backtrace.
