Title:
  Unhandled exception in UpnpService causes crashes

Status in Banshee Music Player:
  New
Status in “banshee” package in Ubuntu:
  New

Bug description:
  With Upnp enabled, Banshee constantly crashes somewhere between 20-45
  minutes of activity. The log tells me it is always the same exception:

  Additionally, this exception is also thrown at intervals but does not
  cause Banshee to crash:
