Bug 249418

Version:           unspecified (using Devel) 
OS:                Linux

I was debugging KolourPaint, got a "floating point exception", but no backtrace (for whatever reason). I clicked "Reload Backtrace" and DrKonqi crashed.

Application: The KDE Crash Handler (drkonqi), signal: Segmentation fault
