Ah, after fiddling around I found out that the "svn update" of the zalchemy 
package resulted in this error. If somewhere in my code zalchemy is used, the 
TypeError emerges. It seems that recently there was a change to the zalchemy 
package (svn log):

using the threadlocal strategy of sqlalchemy instead of creating one engine 
per
thread. This allows connection pooling for instance.

I reverted zalchemy to an older version an all is well again.

Once again it proves that updating only makes sense if an update is really 
necessary... ;-)

Best Regards,
Hermann
