xfce crashes repeatedly after changing icon theme to default

Here's the crash report, I couldn't send it earlier due to a proxy error

I can reproduce this

apparently LP ate my previous comment?
The cursor.theme file shipped by human-cursors-theme that is installed in /usr/share/icons/default/index.theme lacks a Directory= entry as requested by the fdo icon theme spec. This makes the whole Xfce desktop crash. It should be more resilient and needs fixing to be 'liberal in what it accepts' but the cursor theme file need fixing as well.
Just an empty Directories= appended suffices to keep xfce from crashing.

Does this happen with industrial-cursor-theme also? It does not have a Directories entry either.

installed industrial but it does not appear in the icon theme selector. Which is correct since it is a cursor theme. So the prob with human could be that it is named index.theme which is the name of icon them files?

66193 is similar and I reproduced it, and the reporter said that affects gnome as well.

renaming index.theme to cursor.theme solves the problem as well by not even showing this in the icon theme options. I think this is the better solution actually, no need to modify the file.

Fix works on Ubuntu and Xubuntu.

Added:
 Hidden=true
 Directories=

Marking RC, confirmed by Dup.
