For workaround, you could have  used wx.CallAfter like this:
self.vectselect.Bind(wx.EVT_TEXT, lambda evt: wx.CallAfter(self.OnVector,
evt))

which would solve the problem with the hanging combo tree. The info label
is in my opinion better solution anyway and it should be used more often in
wxGUI instead of poping up error dialogs.

If you are talking about the combo layertree behavior, I think it's a bug,
this widget has a lot of other issues.
