Description Luna 2026-01-27 19:41:47 UTC 
SUMMARY

Krita segfaults when creating a new vector layer, after switching to a session. 


STEPS TO REPRODUCE
1. Open a document
2. Switch to a previously saved session
3. Create a new vector layer

OBSERVED RESULT

This causes a segfault in the `DefaultTool::updateDistinctiveActions` call. Specifically what's happening here is the action group for the action `text_type_preformatted` is set to null after the session switch. Tho it only happens every other session switch.
