Thunderbird stalls while sound is suspended
Binary package hint: mozilla-thunderbird
When the (pulse-)audio is suspended by some program (for instance MusiScore, who accesses the soundsystem directly), not only the sound is suspended, but thunderbird (and firefox) stalls untill the sound is produced (this happens after the suspending program releases the sound system) then thunderbird gets reactive again and all is well...
This using the current (and earlier) versions of 8.04, all updates applied.
system sounds are suspended as well, but the system does not stall.
