New crash information added by DrKonqi

DrKonqi auto-attaching complete backtrace.

I have reported a very similar scenario (if not the same) in this issue that has been marked as duplicated:

The bug that was marked a duplicate of has an entirely different backtrace. Also, the bug you linked was for a crash after entering sleep mode. This bug is about a crash after the screen went to sleep, but not the system. The bugs are unrelated.

Key part is here:

Andreas, are you using any non-default icon themes, global themes, plasma styles, etc.?

Hi Nate, I use Oxygen for everything: global themes, plasma style, colors, window decoration, etc. Only the icon theme “Oxygen Mix” is non-default.

drkonqi report of new todays crash 28.oct.25

I've got a new crash yet. But this time, drkonqi reports:
The crash data cannot be collected for unknown reasons. You can try again, close the window, or view the detailed information.

Don't worry about attaching a crash report every time this crashes. The backtrace we have is enough for the developers to work with. If we need more information, we'll ask.

If you look at the information in the attachment you added, there seem to be some system configuration issues. For example:

> 
> warning: Could not load shared library symbols for /usr/lib/libleancrypto.so.1.

Arch is a "built it yourself" distro, and so when things like this happen, users need to fix things themselves. I recommend reaching out on the Arch forums for assistance in fixing these issues, and making Dr Konqui work again.

Looks very very similar to Bug 506642, but it's not exactly the same.

*** Bug 511383 has been marked as a duplicate of this bug. ***

Shouldn't this
| #24 0x00007f28dbfb83ca in KConfigGroup::readPathEntry

just be KConfigGroup::readEntry()  given what the contents look like in 

|#21 0x00007f28dbfaa3d7 in QString::fromUtf8 (utf8=0x55633a5bbe40 "base/8x8/emblems,base/16x16/actions,base/16x16/

I made the change and tested it - haven't been able to trigger any problems but I am not sure this bug was always reproducible or not to others - it's sporadic for me.

*** Bug 512175 has been marked as a duplicate of this bug. ***

Another potential way of reproducing, copied from the duplicate:

---
I'm getting a somewhat consistent crash in plasmashell when unlocking my screen using a fingerprint when returning from sleep. I couldn't get the crash to happen when unlocking with my password, only with my fingerprint. The crash doesn't happen on every unlock, once every 2 unlocks or so.

STEPS TO REPRODUCE
1. Close the laptop lid, the system goes to S2 sleep
2. Open the laptop lid
3. Login using the fingerprint scanner
4. Click the "Unlock" button
---
