The official position is you must use the same SVN revision on all 
systems.  If you use different ones and don't see any problems and 
you're happy, that's fine.  If you use different ones and /do/ see 
problems, it's up to you to verify that the differing versions are not 
causing the issues /before/ reporting any bugs to Trac/wasting the 
developers' limited time (i.e. ask on -users list first, test with 
identical revisions, ...).
