I am seeing the same thing here consistently across all 5 of my work/home computers
please try banshee from dotnet overlay https://github.com/gentoo/dotnet/blob/master/media-sound/banshee/banshee-2.6.1-r1.ebuild
*** Bug 579420 has been marked as a duplicate of this bug. ***
I also see this is forcing the usage of vulnerable mono-2, hence it's fixed to support mono-4 or this will be treecleaned
dropped
