crashes need to have a backtrace otherwise we can't do much.

When you restart you should see a sad face icon in the systemtray - clicking this will open a dialog where you can send a crash report.

Comment 2 Kai Uwe Broulik 2019-10-09 10:48:49 UTC

This is probably https://bugzilla.redhat.com/show_bug.cgi?id=1758263

It's a regression in Qt 5.12.5, Qt 5.13.1, Qt 5.14, and dev:

Comment 3 pipapo 2019-10-09 11:39:21 UTC

Following command is crashing plasmashell as described.

#~: kdialog --passivepopup "foo"

For now the backtrace reads like this:

Application: Plasma (plasmashell), signal: Segmentation fault

Comment 4 pipapo 2019-10-10 10:33:06 UTC

This bug is really annoying in daily work.
As a workaround I deactivated messages for various services.

Comment 5 Kai Uwe Broulik 2019-10-10 10:37:57 UTC

For now either remove notification plasmoid or upgrade to Plasma 5.16 or newer. We're working on it but it is tough.

Comment 6 Justin Zobel 2020-12-06 21:17:40 UTC

Thank you for the report.

As this was reported on an older version of plasmashell, can you please test on a recent and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.

Comment 7 pipapo 2020-12-06 22:03:34 UTC

This issue vanished with this version. I can't reproduce this behaviour anymore.
