You probably want to avoid modal dialogs (in any toolkit) when 
integrating with Twisted.  The require a reentrant mainloop to 
implement, and no Twisted reactor (ie, mainloop) is reentrant.

Whether or not the fact that this is a modal dialog is actually causing 
this particular problem, I don't know.
