Description Ralek Kolemios 2019-08-24 05:12:44 UTC 
SUMMARY
I decided to use the reference tool for the first time. I found it very useful. However, ever since dragging images into my project, said project crashes every 5-10 minutes. It's not tied to autosave, as that's set to every 1 minute. It seems(?) to be tied to using the space-button pan tool, though that may be coincidence as it's what I use the most.

In addition to the random crashing, I can force a crash by trying to remove any of the reference images. Since that's more reproducible, I'll describe that below.

This problem persists on all available versions, most recent 4.3, 4.2.6, 4.2.5

STEPS TO REPRODUCE
1. Import a reference image with the reference tool
2. try to delete it

OBSERVED RESULT
Entire program freezes and windows attempts to send a report

EXPECTED RESULT
It deletes the references

I can confirm this on recent master built from git. Trying to delete the reference image hangs krita.

here is the backtrace from gdb

Comment 2 wolthera 2019-08-24 12:43:54 UTC 
Hey, the delete crash is already reported, so I'll mark this as a duplicate. The other bug you're talking about is separate though.

It'd be super great if you could make a separate bugreport for the other 5/10 minutes crash, and see if you can attach a backtrace as per instructions: https://docs.krita.org/en/reference_manual/dr_minw_debugger.html :)

*** This bug has been marked as a duplicate of bug 411212 ***
