Hi,

This call trace may safely be ignored. This is a known problem and is
harmless. This is documented as a very old bug record. I don't know if
it's accessible externally, so you may not be able to read it:

https://bugzilla.redhat.com/show_bug.cgi?id=790188

It does not relate to the previous error you posted.

Regards,
