[Grok-dev] Wierd deployment error... (ValueError: Empty module name)

[Sebastian Ware]

Hi!

Sometimes when I update the source files on my deployment server, I  
get a "ValueError: Empty module name". What I have done is:

- The application is running on my deployment server
1 deleted the .pyc files
2 overwritten all files except .zcml with files from my dev server
3 performed a "zopectl restart"

The application doesn't start (trace below). I have solved it  
previously by recreating the project from scratch, but what I would  
like to know is what happened.

Note. This error only occurs randomly, and not very often...

Regards Sebastian
