>From this sentence I deduce you don't know *how* the PyQt binding is
generated. It's not a trivial task and the binding layer adds it's own
bugs and glitches, of course. PyQt doesn't interact well with the
Python garbage collector [1] and sometimes you have segfaults *VERY*
hard to be debugged.


[1] I mean: everything works perfectly 99% of times, but problems still persist.
