libvirt users - Mar 2013 - snapshot-create fails with "error: Failed to open file '(null)': Bad address"

Hello.

I'm not able to create a snapshot for none of my vm's running on a 
particular node. And i have absolut no idea where to look to solve this. 
Someone can point me to the right direction?

After downgrading to libvirt-1.0.2 everything works as expected. Is 
this a known issue? Should i open a bug report on bugs.gentoo.org since 
i'm running gentoo?

best regards
