Either way, there's other instances on the lists of this error cropping up, so this circumstance should probably be handled more robustly. In the meantime, workaround?
'm'fraid no. I gonna have to investigate that. Please open a ticket with a self-contained example that reproduces the issue.
Thx in advance...
