DVTool v2.0 beta5 occasionally gets a signal 29 fault on disconnecting an audio feed or when disconnecting a connection.
Ubuntu Linux 12.10
....At which point the application crashes.

It doesn't do it every time. As best I can tell the fault occurs if the app thinks it still needed to pass more audio to the sound card at the time when the disconnect or stop audio tests was requested.
