Pretty much every application will crash like this because pretty much every 
application calls kapp->exec() from main(). The interesting part is the 
function that actually causes the crash, that's typically frame #6 or so:

#4  0x40024bc4 in pthread_sighandler () from /lib/libpthread.so.0
#5  <signal handler called>
#6  0x081d8660 in KMHeaderItem::paintCell (this=0x86245a0, p=0xbfffdcd0,
    cg=@0xbfffdc38, column=0, width=310, align=0) at kmheaders.cpp:286

Frames #1 to #5 are part of the crash-handler itself and will be the same for 
all crashes as well. (Numbers can be slightly different from system to 
system)

Cheers,
Waldo
