Short description of error

Blender crashes when scene doesn't have any meshes (no cube) and when you use command searcher (F3 default hotkey) in 2 possible ways to cause Blender crash.

Exact steps for others to reproduce the error
One way:

  1. Open default scene, delete Cube
  2. Open command searcher (F3 key), type "e", then "x" - on that last key Blender should crash

Other way:
Same as above, except instead pressing "x" key, scroll down to list bottom. When it reaches end of list, it crashes Blender

Out of curiosity, checked 2.82 alpha version and there were no issues

I've attached .blend file where I was testing crashing. But just deleting all meshes in your default startup scene should do the trick. I've asked in Blender discord and one person confirmed crashing.

Can I hope for fix before 2.82? :D



Event Timeline

This was fixed, see T71932: Crash when type "ext" in search.
And you already noted, that this works fine in 2.82 alpha, so... not sure what you are asking?

Can I hope for fix before 2.82?

Yes, 2.82 alpha daily builds...

I meant to ask if this could be hotfixed in 2.81. Especially if there's already an fix. 2.82 alpha isn't production ready and it will be months before reaching this point. Thanks.

No, no backport fixes.

2.82 is scheduled for February.
There will be a 2.81a bugfix release soonish though, we might consider to include this fix in there as well?
