Hi Eric,

Could you please file this upstream as well, at https://bugzilla.gnome.org/enter_bug.cgi?product=banshee ? We don't really have anyone fixing issues with Banshee code at Fedora and you'd get more feedback at upstream.

Thanks, and sorry for the inconvenience.
Comment 2 Eric Christensen 2014-03-12 03:43:06 UTC 
External bug filed.

Upstream patch.

This is the patch from upstream.  I've tested the fix and I'm not able to reproduce the original problem (although it was intermitted at worst).

Upstream says this fix should be shipped in the next release but I'm hoping we can go ahead and include it as a patch temporarily until the fix is offically shipped.
Comment 4 Kalev Lember 2014-05-21 20:03:12 UTC 
Looks good to me, thanks. I've pushed this and builds are underway.
