Unfortunately, I could not reproduce the crash, but the preprocessed
file you sent confirmed Matthieu's diagnosis.  The file contains:

#  if _MSC_VER < 1310
#     define QT_NO_QOBJECT_CHECK
#     define Q_TYPENAME

And Clang defines _MSC_VER to 1300.  But in my opinion this code path
should not be executed for Clang because Qt 4.7.4 has support for
Clang, one should just select appropriate compiler configuration
(during Qt compilation?).

There's also a bug in our crash report generation.  Note the
mismatched quotes and the inappropriate "Files\\..." part in:
