Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu Natty (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

While downloading Avant Window Navigator from Get and Remove software, any time I click cancel on the download the whole application crashes and needs to be reopened.
