Comment 1 for bug 833717

Couple of weeks ago I tried to build a Windows package from latest sources and go the same error under Windows XP and Windows 7. I tried Python 2.6 and 2.7 - no difference same error.

I think that problem is with PyQt features. It looks like PyQt that supplied by Riverbank for Windows platform has Acceptability features turned off.

After trying for a while (recompiling Qt and PyQt on Windows, which didn't work well), I give up on this problem.

I hope Koo will move away from PyQt to PySide, which is a true open source project comparing to Riverbank. Just try to find sources for older version of PyQt - good luck :(
