ADDITIONAL INFORMATION

Comment 1 Nate Graham 2021-06-08 19:22:40 UTC

Cannot reproduce. Can you please attach a backtrace of what System Settings is doing when it hangs? To do this, you would need to launch the app using gdb, like so:

`gdb /usr/bin/systemsettings5`

Then type "run". When it freezes, type "bt" and then paste the full output in here.

Hmm, that doesn't tell us much. :/

Comment 4 David Edmundson 2024-09-16 11:06:07 UTC

It could be the issue of an existing systemsettings not exiting properly that we've seen with the GHNS issue. Please reopen if an issue persists with Plasma 6.2
