[Bug 86282] Theme previews go away after installing new widget themes

[Donald Straney]

Public bug reported:

Binary package hint: gnome-control-center

In GNOME's theme switcher (GNOME Control Center version
2.16.1-0ubuntu4), the theme previews change to question marks after I
install two widget themes in a row by dragging the .tar.gz files to the
theme list.  When prompted to switch to the new theme or keep the
current theme, I always choose to keep the current theme, and the
previews are shown as normal again after I close the theme switcher and
re-open it.  I've been able to reproduce this every time, and it doesn't
happen with icon themes - when I install two widget themes in a row, the
previews go away after the second one is installed, but when I install
an icon-only theme and then a widget theme, nothing happens until I
install another widget theme.  In case it matters, the theme I used
while installing these was Mist, and there were no third-party themes
installed in ~/.themes.  If it would help, I could attach a tarball of
the exact themes I was installing.

** Affects: control-center (Ubuntu)
