[Grok-dev] Debugging a ZopeXMLConfigurationError (ValueError: Empty module name)

[Sebastian Ware]

I have been developing an application on my laptop and when I try to  
deploy it I get a cryptic error (ValueError: Empty module name)  
during startup. Any ideas on how to debug this? It runs fine on my  
laptop. I first assumed that it had to do with new parts of the code  
requiring Reportlab, but the error persisted even after I had removed  
the reportlab specific code.

Any ideas on how to debug this?
How do I know what the error is refering to?
