Description of problem:
When running any of the available gnome-shell themes other than Default, if I type anything into the search window the GUI locks up.  I have to kill the X session or kill the gnome-shell process in a console to escape.

Version-Release number of selected component (if applicable):


How reproducible:
Every time

Steps to Reproduce:
1.Change gnome-shell them using gnome-tweak-tool to anything other than default
2.click on "Activities"
3.type a few letters
  
Actual results:
GU locks up (except for mouse movement).  If I switch to a pseudo tty and check top the gnome-shell process is now taking 100% of cpu and will continue to do so until I kill it.

Expected results:
performs the search

Additional info:
I've tested with both the Nouveau and proprietary nvidia drivers (using Nvidia Geforce 210 video).  Dual display, with both video drivers (twinview using Nvidia drivers).  I've tried it with the shell themes Atomlm, Dark Glass, Gaia, and Orta.  No errors in /var/log/messages, Xorg.0.log or dmesg.
