-- Information about the crash:
Running a screen session under Konsole. I was selecting some text with the
mouse to copy it over clipboard. 
Steps to reproduce: 
- Konsole with two tabs. 
- screen session under fist tab with many (10) screen subtabs
- run some command with a lot of text.
- Shift+PgUp to roll up.
- Start selecting text with mouse. 
- Move cursor below forcing to go to current terminal cursor.

Expected behaviour:
- Text selected, and available through clipboard. 

Current behaviour:
- Konsoled crashed. 

Couldn't reproduce later (few tries).

-- Backtrace:
