- What is your widget style ? 
- Does Konsole crash again if you repeat the situation ?

I have a custom profile for konsole.Only changed appearance settings, otherwise it's the default.

I can reproduce the bug by trying to open a new tab. It crashes if I double click on the tab bar or press Ctrl+Shift+T, no matter what's open in it. (I initially thought nano was somehow involved, but it's not true.)

[Comment from a bug triager]
> - What is your widget style ? 
I mean the KDE/Qt widget style (you can check it on SystemSettings/Applications Appearance/Style)
- Does the crash happen with another Konsole style/profile ?
Regards

Comment 4 Kurt Hindenburg 2011-03-05 22:52:14 UTC

Attach the profile you are using to cause the crash.  Also try later KDE version if you can.

Comment 5 alexboly 2011-12-30 11:45:50 UTC

I couldn't reproduce the bug anymore.
