-- Information about the crash:
What I was doing when the application crashed:
- I had multiple tabs open in Konsole - which had been open for ~24 hours
(locked computer overnight and returned to the consoles the next morning)
- I was attempting to reorder the tabs and accidentally double-clicked while
dragging a tab to re-order it.
- Konsole crashed after that double-click action occurred.
- I have not been able to reproduce this crash.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
