I just recently ran into this problem too and figured it was nuke deleting my
object, so my hack was to do something like this:
myMenu.addCommand("My PyQt Window", "t =PyQtTest.myDialog();t.show()")
I'm sure there is a better way as well but I just haven't looked that hard into
it, so I'm looking for an answer too!
Thanks!

Subject: [Nuke-python] Re: Nuke6.3v1 and pyqt from menu bar
Hi,
So I think I figured this out. The QLabel object no longer exists
outside the scope of the function so when the funciton returns it
cleans up and deletes the QLabel object. One way around this which I
found from the pyQtRender2 example is to add a nuke callback that
calls the QLabel(makes more sense here if we are talking about
dialogs) object hence keeping it alive. I am sure there is a better
solution but that works for me.
Regards,
Gerard Keating.
