Guns of Icarus Online voice chat crashing steam

[nake90]

Hello I've already reported this bug to the Guns of Icarus developers, but as it is also crashing steam (closes with a memory error) I thought I should report it here too.

The bug appears at random when playing and clicking the push-to-talk key. When that happens, the game freezes and if you Alt-Tab you'll see that steam is no longer running.

The console that I used to start steam says:

System startup time: 16,63 seconds

Most likely the same problem (even though it's a different game) as #1853.

Some users have reported that disabling or removing pulseaudio avoids the crash. I understand this isn't a solution, but it's an interesting thing to test to try and localize the problem. If disabling pulseaudio avoids the crash you should report your experience to the pulseaudio folks.
