[PyQt] sipEnumType_alloc: Assertion for PyQt5 but not PyQt4

[Guðjón Guðjónsson]

Hi Dmitry

Thanks a lot for your help. I tried to make a smaller Qwt library that
would reproduce the bug and then for some reason I got a much more
interesting backtrace, see attachment.

Is there any more analyse I can do or shall I hope that Phil helps?
If I compile the same code with PyQt4, import Qwt works nicely.

Regards
Gudjon
