I was able to track the issue down to this, and this message contains a 
temporary workaround to eric:

Hopefully, you're able to apply the diff, it's around line 1261. With 
it, you're able to use eric again.

OTOH, I'm too busy at the moment to investigate for a real fix to the 
issue. Interestingly, you're on win32. Could you document your 
environment a bit more, e.g. OS version, where do your packages 
Python, Qt, sip, and PyQt stem from, or how do you built them yourself 
(including logs, if possible). That would be really helpful to narrow 
down the circumstances, where this issue appears..

No it's not, and this sounds strange. You may want to play with the PyQt  
examples a bit to check for other deficits.

No, this won't fix your issue, since it is something related to sip, or 
rather the way, that sip is built.
