I use 6848 (today's version as dorsal does a svn update within an 
existing mtl4 directory)

Oh yepp right, accidentally looked and copied the messages from the 
second run...

Just investigated the problem and there were a changes in the mtl4 
trunk, updating to your revision actually resolved the problem (note to 
me: should have done this first :))
A svn diff of the revisions showed that basically the implementation of 
the function num_rows and num_cols were changed.

Oh man, installation of bleeding edge software makes always fun and gets 
you never bored :)

Thanks for the help!
