--- Comment #2 from Todor Petrov <[email protected]> --- 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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
