I am using:
Python2.7
Python-Libvirt 1.2.2 with the "[PATCH libvirt-python 1/2]
setPyVirTypedParameter: Copy full field name" patch.
Libvirt 1.2.1
Is the following patch applied as well?

setPyVirTypedParameter: free whole return variable on error
The @ret value is built in a loop. However, if in one iteration
there's an error, we should free all the fields built so far. For
instance, if there's an error and the previous item was
type of VIR_TYPED_PARAM_STRING we definitely must free it.

Can you install debuginfo so we see the full stack trace?
