In my experience with running KDE 3.5 apps inside KDE 3.3 session, it's also
necessary to 

     export KDESYCOCA=<kde3.5-specific-dir>/sycoca
     kbuildsycoca

Otherwise, I get errors about old format of sycoca database, and 3.5
KDevelop can't find its plugins, and generally nothing works. Is this
indeed required, or I'm doing something wrong?
