GTK applications will not start after update

[Bo Milanovich]

I am unable to access Ubuntu right now due to this bug so apologies if I am not able to provide you with all the details. Running 13.04

After today's update, I have noticed that I am unable to launch GTK applications. When trying to launch from terminal, this is the error I am getting:

symbol lookup error: /usr/lib/x86_64-linux-gnu/libgdk-3.so.0: undefined symbol: wl_registry_interface

The relevant library is symlinked to libgdk-3.so.0.600.4 in the same folder. The locate command reports no other instances of libgdk on the computer except for those two.

None of the GTK apps work, including Unity-greeter, causing me to be unable to log in (and even if I logged in, I assume I would not be able to have a usable DE). Thought a reboot might help, but it did not.

I am able to use Windows on the same computer and have Ext2Read installed, so let me know if I can pull any relevant logs for you (Xorg.0.log contains no (EE) entries).

Also, I am not sure if this is actually relevant to the gtk2-engines package. But Launchpad wouldn't let me submit the bug with the "I don't know option", or the libgdk-3-cli package.

Status changed to 'Confirmed' because the bug affects multiple users.
