[Bug] Modifying selected Tiling style fails to apply and/or causes PlasmaZones Settings to crash

[Zoxjib]

Description

I was trying to configure the 3 Columns tiling style from 5 to 7 using the slider. Sometimes it saved, sometimes it crashed, sometimes the setting reverted back to 5. When this was going on, it also prevented me from modifying anything with the same style in the Layout Editor.

At some point it started working, and I thought it was by modifying a Tiling style that wasn't selected as the active style at the time, but I'm not sure the behavior and crashes seemed inconsistent.

Expected Behavior

Modifying the tiling zones without crashes

Steps to Reproduce

1. Selecting a Tiling style
2. Go to the Tiling menu and adjust the sliders to add/remove extra tiles or modify the tile sizes
3. Save
4. At this point it might crash
5. If it didn't crash, go back to the Overview menu and it might also crash

Thanks for the report and especially the support report, it made the config side of this diagnosable.

I found and fixed the part where your change fails to stick. Your config showed the three-column style's max windows saved as 7, but the daemon could overwrite it back to 5 whenever a settings reload also switched the active tiling style. That is why it seemed to work when you edited a style that was not currently selected. The fix is in #854 and will be in the next release.

The crashes are a separate problem and unfortunately the support report does not capture a crash trace for the Settings app. If you can still reproduce a crash, could you run this afterwards and paste the output here?

coredumpctl info plasmazones-settings

If that shows a recent crash, the output of the following would be even better (type bt at the gdb prompt, then quit):

coredumpctl gdb plasmazones-settings

The Layout Editor refusing to save was most likely collateral from the same bug. The daemon was busy churning through the corrupted reload cycle, and editor saves time out when the daemon does not respond quickly. That should also improve with the fix.
