seg fault

[Ajay]

hi!

i have some code with a gui that does some processing in another thread,
say t2.
when t2 needs to display something on the gui, it generates an event (which
i have binded earlier). the code runs fine on windows but segfaults on
linux.
the point where it segfaults is when it generates the event.

any ideas why?

the code is

#app.py

sys.path.append('\\Program Files\\Python\\Lib\\python23.zip\\lib-tk')
