Bug 383997

Application: yakuake (3.0.4)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.12.8-1-default x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:

When I was trying to copy from a very big portion of a maven output by selecting lines top down (probably around 75000 of the 100000 lines I enabled for the scrollback), yakuake crashed before I reached everything I wanted to copy. I was still selecting (via mouse) while it was crashing.

- Custom settings of the application:

scrollback set to 100000 lines

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
