This is already tracked in upstream issue mumble-voip/mumble#3281 and a
fix has been merged in mumble-voip/mumble@caa187373e.
The patch I'm adding here is using the merged commit
mumble-voip/mumble@ea861fe867 and I've
only added it for the stable release because the patch is already
included in the git version.
@pbogdan also had a similar commit to this
(pbogdan/nixpkgs@8029edea29), but the
patch was applied to both stable and git and thus the git version would
have been broken.
Tested by building mumble and mumble_git and running the mumble NixOS VM
test.
