Comment 8 for bug 840306

I can confirm a hung qaptworker process when using Muon and Etckeeper (git backend; don't know if that matters). My process list shows Etckeeper trying to run its post install hooks:

Although the commit appears to not have completed, running git log on the /etc directory shows that it has actually done so.
