Did you run a "make install" afterwards, just to make sure the ui files are installed properly?

Hmmm, strange…

…even more strange.

Looking at the code, I get the impression that it actually doesn't do something sensible.  Peter?  Shouldn't we just remove this stuff?  Or what's its purpose?

Yes, it's completely broken.  The stack corruption might have been caused by an overflow or similar.  Do you have Valgrind installed?  You could try to run Balsa in valgrind (note that it will run *extremely* slow, as Valgrind will catch all mem operations!) by calling

valgrind --log-file=balsa-vg.log src/balsa

and then check the log file if it reports any memory errors.  Somehow a little stabbing in the dark, I'm afraid, but these issues are typically difficult to track down…

Cheers,
Albrecht.
