Comment (by nigel):

 export DYLD_PRINT_LIBRARIES=1 reveals that these problems are due to Qt
 plugins:

 On Mac OS X, you might be loading two sets of Qt binaries into the same
 process. Check that all plugins are compiled against the right Qt
 binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of
 binaries are being loaded.

 }}}
 i.e. moving .osx-packager/build/plugins out of the way removes the
 warning.
 [[BR]]
 The only plugins that we load are the image ones, and
 http://code.mythtv.org/trac/ticket/8898 says that QImage uses
 QCoreApplication::libraryPaths() to locate its plugins. The doc for that
 class now hints that qt.conf can override the defaults.
