Unhandled exception in UpnpService causes crashes

[Philippe Moreau]

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

Sounds like you have a broken UPnP device (a router?) on your network, and this
is causing Banshee to crash here.

[Philippe Moreau (philippe-moreau-1)]

Thanks. The broken device is XBMC.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Simon Lock (aergan)]

Having the same issue. When crashed, Banshee will refuse to open again or show a frozen blank GUI window.

It will refuse to open again until ~.config/banshee-1/banshee.db is deleted.

Also using XBMC (13.0)
