Bug 305571

Application: muon-updater (1.4.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.2
Operating System: Linux 3.5.0-11-generic x86_64
Distribution: Ubuntu quantal (development branch)

-- Information about the crash:
Both muon and muon-updater crashes when I click "install updates" or "apply changes", same happens while clicking "check updates".
Sorry for my english.

The crash can be reproduced every time.

-- Backtrace:
Application: Модуль Muon для управления обновлениями (muon-updater), signal: Aborted
