Description Alexander Schilpp 2025-11-28 10:49:02 UTC 
SUMMARY
Krita crashes on "Paste" when copy-pasting on macOS, while Copy 'Em (clipboard manager for macOS) is running.

STEPS TO REPRODUCE
1. Install and run "Copy 'Em" (https://apprywhere.com/ce-mac.html or from App Store)
2. Open any image file in Krita
3. Select area, copy + paste

OBSERVED RESULT
Krita stops (crash)

EXPECTED RESULT
Pasting the copied image as new layer

SOFTWARE/OS VERSIONS
Windows: 
macOS: Sequoia 15.6.1
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

Copy 'Em: 3.1.1

ADDITIONAL INFORMATION
I have contacted the developer of Copy 'Em, and his response was:

"I think this is something the developers of Krita should look into,
because normally, apps shouldn't crash. If an app crashes, it means it
fails to handle certain cases correctly. Given that Krista crashes on
"Paste", it's likely that it fails to handle the pasted data correctly."
