Bug Description

This happens on a regular basis. I open mumble, and when I try to connect, it hangs. This doesn't happen every time, but maybe 1 out of 2. Usually killing it and starting again works.

Adding an upstream task in case there is an upstream that wants to take a look. Mumble is not in our main repository, atm, so Ubuntu Engineering will likely not be working on this specific issue.

I just switched Mumble to use PulseAudio instead of Alsa and it seems to fix the issue for me.

Started happening to me and a large number of people I use Mumble with whom I asked after upgrading to Raring.

We're hoping to fix this upstream as soon as we can.

The hang happens inside avahi's libdns_sd compat library. The library gets in a weird state because of a seemingly wrong readyRead() by a QSocketNotifier in Mumble's Bonjour code.

We haven't found the root cause of it yet, though, but we hope we will soon.

Can Ubuntu maintainers update the package?
