Glade crashes when running “quickly design”

When I run quikly design Glade opens and starts loading all my UI files. After a few seconds of loading each file it crashes silently (no error message or command line output). The Glade window is just gone. Running Glade normally doesn't result in a crash. Running it this way, however, without running quickly design I am obviously not able to graphically edit my application's GUI using Glade.

I have tried re-installing (and purging) quikly and all its dependancies with no luck. I have also tried creating a fresh blank new application (using the quickly create ubuntu-application command) with the same results - i.e. Glade crashes silently.

In addition I have tried my best at some Googling to resolve this problem, with no results.

I am running an updated Ubuntu 12.04 with Unity removed and KDE installed (from the kde backports PPA).
