I don't know if this is relevant to the crashes you have been getting, but
TraitsUI and most other Enthought Qt-oriented GUI projects use version 2 of
the SIP QString and QVariant APIs:

    https://github.com/enthought/pyface/blob/master/pyface/qt/__init__.py

This is done so they can swap between PyQt4 and PySide without hassle and to
get better unicode and Python 3 support. QGIS uses Version 1 of those APIs
which is fundamentally incompatible. QGIS could upgrade to version 2 but all
Python plugins containing code using QString or QVariant would have to
replace these calls with plain Python strings and objects---definitely a
"2.0" sort of change.
