Bug 364685

Application: konsole (16.04.1)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.7-300.fc24.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I run a PyQt5 application that allows Konsole processes to be created.

Maybe this is related to the crash.

I am happy to test patches that investigate the problem of may fix it.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
