Thanks for the reply - I was afraid of this. IMHO this is a huge limitation 
for pubsub.

Can the issue be worked around by calling wx.CallAfter on all functions 
updating the GUI? I'm using this solution now, and it seems to be working, 
however from experience such features can blow up in your face after some
