This sort of reminds me of an issue I'm having the current WINE package in Debian. The wine64-bin package contains only a text file describing what's necessary to install the i386 foreign architecture and then to install the wine-bin:i386 package. And then there are some problems from there because of the 64-bit OpenGL libs vs 32-bit ones. I likewise haven't been able to work around those issues yet (but it's been a low priority), and I have not found it easy to find documentation on how to do so. > > > I'd like to wait for Chris' additional tests in a VM without OpenGL > > > to make sure that the mumble binary itself still works there. > > > Then I'm happy to upload the package. > > > > Ok.

To be on the safe side I suspended compositing on the host and made sure the VM didn't have 3D acceleration available. Starting mumble on the command line I get a whole bunch of audio-related errors which I'm going to assume are not important for the libGL issue so I'm filtering them out. [I did verify that audio connectivity between the VM mumble client and the host mumble client worked through the server at least in one direction.] $ cat mumble-test.txt | fgrep -v "ALSAAudio: Non-critical: avail = snd_pcm_avail_update(pcm_handle): Broken pipe" G15LCDEngineUnix: Unable to connect to G15Daemon.
