Hi,

I worry about moving to SVN.  I'm not sure it's that mature.  Here are my 
recent experiences with 1.1.3 (for a non-KDE project):

[clarence@celery ours]# svn diff -rBASE:HEAD
Segmentation fault
[clarence@celery ours]#

If you are interested in the details, see the attachment.  Looks like it gets 
confused with a file deleted in another checkout.  I don't yet have time to 
try to reproduce the bug and file a report with the SVN developers.

Clarence
P.S. I am deep in assorted work and may not reply for a few weeks.
