Short description of error
When I create a new scene and try to set the
proxy_storage
property of the first scene in the console (or a script/addon) with:I get a Segmentation fault. I tried running with "--debug-all" option but no more clue from it (and I did not have time to investigate further with a debug build of blender).
Exact steps for others to reproduce the error
D.scenes- [x].sequence_editor.proxy_storage = "PER_STRIP"
in a Python console area and press enterNow, if you select the first scene before running the line of code, no more crash. If you select again the second scene and enter the line of code, crash.
If you managed to have a sequence_editor created for the second scene (I did it by adding a Text effect strip inside, it seems to trigger the creation of the sequence_editor), then the line of code works and produces no more crash. (but then if you create a third scene and reproduce, then you got a crash again).
