Application: muon-updater (1.2.80 "Daring Dalek")
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

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

I just added the kubuntu-ppa/beta repository to my list of sources, so I can run the RC.  I did a package refresh once, then checked all the boxes that were unchecked, then refreshed again.  I was given a rather unspecific error, and then muon updater crashed.

PLEASE NOTE: I am running the beta version of muon from the test repository.

-- Backtrace:
