Crash when deleting source file, reload file and undo
Steps to reproduce:
- Place an import an image (not a movie!) file to the project
- Drag image to the timeline
- Remove image from filesystem
- Trigger "Reload clip" on the on the right click menu in project bin -> you get an error message and the image will be removed from the timeline and the project bin
- Trigger undo -> crash!!!
If you do the same with an video clip, on Step 4 it isn’t removed from the project bin and on the timeline it is resized to a 1 frame large piece. If you trigger undo, it gets his size back and the monitor shows only white (which is okay, because its the default on a missing clip)
Expected behavior:
The image should behave like the movie, but the movie should not be resized (just keep its size)
