Bug 423054

Created attachment 129412 [details]

I just tried, and can't reproduce the crash.
the backtrace you gave is not really userful because the debug symbols are
missing, can you install them and if it crashes again, attach a better
backtrace?

Luckily for me the application has managed to crash once again in short period. This time I've installed additional debug symbols which I hope will shed a little bit more light on the situation. 
This time however the problem occurred after switching back and forth between konsole window and different application.

Here is the stack trace:

Application: Konsole (konsole), signal: Segmentation fault
