Bug 291479

Application: muon (1.2.1 "Caustic Carrionite")
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-030200-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
Muon selected updates, I clicked the wrong button then clicked on the upgradeable filter, then "apply" and Muon crashed.  It looks like the upgrades were successful.

-- Backtrace:
Application: Muon Package Manager (muon), signal: Segmentation fault
