Short description of error
When trying to open .blend file from python console using bpy.ops.wm.open_mainfile(filepath='/path/to/my/file.blend', load_ui=False), it freezes. From blender output in the terminal I can see that it reloads my file in the infinite loop:

Read blend: /path/to/my/file.blend
Read blend: /path/to/my/file.blend
Read blend: /path/to/my/file.blend
...

Exact steps for others to reproduce the error

  1. Open Python console in Blender
  2. Run (with correct filepath):
bpy.ops.wm.open_mainfile(filepath='/path/to/any/valid/file.blend', load_ui=False)
