On a related note, some kind of path name limit struck me once during 
migration of an 1.2.x wiki to 1.3.x. The wiki directory was mounted via 
NFS, and maybe due to this to a comparatively low limit on filename size 
was in force (maybe 128 characters?).

Since the migration scripts are buried deep in the MoinMoin package 
hierarchy and the data folder is supposed to be copied there, paths get 
very deep very quickly. In my case the path was something like
/export/home/helmert/lib/python2.4/site-packages/MoinMoin/scripts/migration/data/pages/PythonKurs_2f_dcbungenLektion10/, 
which was enough to make Python crash with a segmentation fault, 
something I've never seen Python do before.

Maybe a warning should be added to the migration page?
