data: Drop misleading ExpansionError exception

This codepath can be triggered by a python indentation error for example.
Showing it as an ExpansionError is misleading.

Change the code to add a warning about where the failure came from (in
particular giving the variable key name that triggered it) but raise the
proper exception.
