Description John Apple II 2020-08-20 02:22:50 UTC 
Application: konsole (20.04.1)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.7.14-200.fc32.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 32 (Thirty Two)"

-- 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
Using host libthread_db library "/lib64/libthread_db.so.1".

Hi, Justin,

  No, since my upgrade to Fedora 36 and the latest Plasma updates, I have not had this issue recur.
