- What I was doing when the application crashed:

Just added new repository, then, after updating muon crashed.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jonathan Thomas (echidnaman)]

Is this crash reproducible? It doesn't look like anything that could/should crash, from the backtrace.

[Jonathan Thomas (echidnaman)]

Actually, this could be a bug with QStringBuilder bug: https://qt.gitorious.org/qt/qtbase/commit/fbee9834dc0fa1838a38e552eddd941af1ef39ac?format=patch
