kwave 19.12.2 is still crasing when closed on Arch Linux.

Comment 3 mshmm 2020-03-25 16:09:58 UTC

Same issue here of Kwave crashing when closed on Kubuntu 19.10 with Kwave 19.12.3.

Operating System: Kubuntu 19.10
KDE Plasma Version: 5.18.3

Comment 4 mshmm 2020-03-26 09:12:08 UTC

Terminal output:
~$ kwave

This is kwave v19.12.3 (compiled with KDE Frameworks 5.67.0)

Comment 5 Thiago Sueto 2020-11-02 20:19:33 UTC

Cannot reproduce this on KWave 20.11 from master.

Comment 6 Patrick Silva 2020-11-02 20:44:46 UTC

I also can't reproduce with kwave 20.08.2 on Arch Linux.
Let's consider this bug fixed.
