If this can easily be overrided by setting sys.excepthook, big +1 for
it from me.

Applications with a custom exception handler won't break, and
applications without a handler (which are already broken) will fail
loudly rather than silently, just like anything else in Python.

Still I think qFatal should be used (even when sys.excepthook is set)
in the few places known to cause segfaults otherwise. An exception
message and qFatal is still better than a segfault without any message
(and random coredump).
