With the updated qtagg backend, which worked fine on my OSX box but I
didn't test on my linux box, I get an error when trying to run a qtagg
plot (the previous backend does work on this box, so I think my qt
install is OK)
The offending part is "argument 1" of
a = qt.QAction( qt.QIconSet( image ), text, qt.QKeySequence('M'),
self.window )

Also, the original intent of the backend_version variable was to
report version info for the underlying toolkit. Eg
backend_version = qt.PYQT_VERSION
the backend is assumed to have the same version as the mpl parent.
