Please do not cross-post between users@ and dev@. This is really a
usage question (not about the development of subversion), so belongs
on users@.

[ I've left dev@ in cc for this one reply, please drop it from further
replies. ]

Can you just try it with Python 2.x (2.7 for instance)? I don't know
details about the script, but just know that Python has changed quite
a bit between 2.x and 3.x (and this script certainly pre-dates python
3.x).

Further: as you have probably read in the svn faq entry: to avoid this
issue be careful that all the svn clients you use are from the same
major.minor version (e.g. all 1.6.x clients, or all 1.5.x).
