Comment 18 for bug 24280

From my experiments is not about personal settings.
If I copy the themes to /usr/share/themes it can use them.

The program seems to lie with user-installed themes.
Currently, the correct theme _is_ selected, it is just not always available in /usr/share/themes or /root/.themes

My current workaround:
  - replace all users' ~/.themes with a symbolic link to /usr/share/themes.
  - changed the permissions to allow /usr/share/themes to be altered by all desktop users.

I wonder if this really creates a security issue?
