internal error - invalid characters

[lejeczek]

Hi guys.

Have you seen something like this below?
...
internal error: The string resource has invalid characters 
in its value
internal error: The provided value contains invalid 
characters: Solarstorm SFN5162F SFP+ Server Adapter

this if from journal logs.
This hardware model of the NICs which comprise make up a 
team/bridge which libvirt net use, but what would 'libvirtd' 
bother with that?

many thanks, L.
