Description Michael Dodge II 2016-08-23 22:28:31 UTC

Upon using (Super+Tab) to open the activities menu, clicking the settings button on the current activity will open a settings dialog, in which if I release the Super key without closing the dialog, it causes a segfault in Plasma, causing it to crash and restart.

Reproducible: Always

Steps to Reproduce:
1. Press key combination (Super[windows key, on a common keyboard] + Tab), hold down Super
2. Hover your cursor over an activity that is displayed, a settings button should appear
3. Click the Settings button, which will open a settings dialog.
4. Release the super key _without_ closing the dialog via "OK", "Cancel", etc.

Actual Results:  
Segmentation fault in Plasma, causing it to crash 

Expected Results:  
Activities sidebar should disappear, with the dialog still intact

Software:

Kubuntu 16.04
KDE Plasma 5.5.5
Qt 5.5.1
Linux 4.4.0-34-generic
64-bit

Hardware:
Intel Pentium 3825U @ 1.90 GHz

>KDE Plasma 5.5.5

This is quite old, I know the activity manager got some fixes with regards to the dialog in revisions since. 

Please reopen if you see this with a newer version.
