Version of the application: 2.0.81
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64

What I was doing when the application crashed:
Kile crash when reloading a file which has been modified externally.
I use aspell to spell check my file, so kile detects the modification and crash when reloading the file. This happen randomly.
