Nothing in 0.22 should be using QT3. Check you haven't still got some
old plugins left around from 0.21 that have not been updated to 0.22
versions. MythPhone is a common one since it has been removed from 0.22.
MythFlix could be another depending on which branch you are using.  You
will usually find the plugins in /usr/lib/mythtv/plugins/ or 
/usr/local/lib/mythtv/plugins/.
