Sure enough, I can't reproduce it today. I reproduced that effect 
several times yesterday, or else I would not have reported anything. 
Trying the very same steps today the tests succeed on the first run. 
Only differences between yesterday and today are be:

- I installed git 1.5.6.2 now (had 1.5.6.1 before) under $HOME, with 
PATH, PERL5LIB, LD_LIBRARY_PATH set accordingly; but tests should pick 
up git stuff from the local build dir, right?

- There may have been an automated update to kubuntu meanwhile, but I 
don't think so; cvsps is under $HOME anyways, and what else would 
matter? Perl version maybe?

So it's WORKSFORME now. Sorry for the noise. Next time I'll not only try 
to reproduce (as I did) but wait a day also!

Best
