darktable 5.0 crashes on paste of stack to different image

[cycomanic]

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Paste of history stack to a different image on the filmstrip below the main image inside the darkroom reliably crashes darktable 5.0 on arch linux for me. Stacktrace below (not terribly informative):

Steps to reproduce

1. Open image in darkroom
2. copy edit history
3. paste to another image on the filmstrip below
4. darktable will freeze and shortly after close

Expected behavior

Backtrace shows that the crash involves turning off the busy cursor; I think this has been fixed in Master.

Can you try running a nightly build?
