Hi,
I'm getting segmentation fault randomly in my desktop app for fremantle and I just couldn't figure out what's causing it and the exact source code. I'm using gtk+, gdb and maemo-summoner in scratchbox. Following is the error message and the backtrace from gdb: Thanks

Code:

Program received signal SIGSEGV, Segmentation fault.
