This could be a bug in eric exposed by recent SIP changes - or it could just 
be a bug in those recent changes.

Until recently a call to a C++ virtual method explicitly scoped the name of 
the method called, ie. if foo is virtual method of class bar then...

    self.foo()

...resulted in...

    sipCpp->bar::foo()

...being executed. Scoping the name prevents virtual loops. This has been 
changed so that...

    self.foo() executes sipCpp->foo()

...and...

    bar.foo(self) executes sipCpp->bar::foo()

I think the new behaviour is correct and gives the programmer explicit 
control. It also means that programs stand a better chance of working with 
derived classes that haven't been wrapped (plugins for example). Two of the 
PyQt4 examples need this change in order to work.

One of my own applications demonstrates the recursion behaviour so I'll take a 
look when I get the chance.
