nautilus (with SuperUser rights) crashed...

[Bash]

1. Nautilus crashes every time you select any folder and clicks “Properties” in context menu.

2. Nautilus crashes every time you select any file and attempts to change current owner permissions.

In both cases, the program reports the same error: that current user doesn't exist (see attachment; system was loaded under “live session user”).

Error in terminal:
“ERROR:nautilus-properties-window.c:1836:schedule_owner_change_timeout: assertion failed: (NAUTILUS_IS_FILE (file))”
