Muon Updater crashes every time

[Fernando]

OK, so now Muon Updater decided it wouldn't run anymore. I just noticed because a few days had passed with no updates, which I found strange. I tried to manually check for them and Muon Updater crashes whenever it starts checking.
I have to say, never before had so many problems after upgrading...

My Muon crashes only when I want to upgrade
