[PyQt] pyuic4 strange behavior

[Marco Fabiani]

Hello,

I am trying to generate some python code from a Qt Designer file with 
pyuic4. In my GUI I have a custom widget written in python (see another 
of my posts).
The code of the custom widget start with the usual "from PyQt4 import 
QtCore, QtGui".

Now, if I run pyuic4 I get this error message:

---
Traceback (most recent call last):

     raise WidgetPluginError, "%s: %s" % (e.__class__, str(e))
WidgetPluginError: <type 'exceptions.NameError'>: name 'QtCore' is not

I tried to play around with the widget's file, and surprisingly if I 
change the custom widget code to "from PyQt4 import xxx, QtGui" (where 
xxx can be anything except QtCore) I manage to get my python code 
generated, and it also appears to work...

Is that a bug?
