Right, the error was, that the data.list style always created a new
defaultstyles instance. And the error message itself is fine: it
occurs when you mix data instances with different defaultstyles
without providing an own style list. It is just unclear how to iterate
the styles in such a case.
Somehow I introduced this bug during some rework in the data handling.
It is now fixed in CVS head (data.py rev 1.46). Thanks a lot for the
report.
