The method in question is rather long, so I cannot rule this possibility 
out for sure, but at a first glimpse I could not spy such a method call.
What seems strange to me is that the back trace shows debug symbols 
further down, even for the gui library. This looks like code from two 
separate instances of gui gets loaded. Could you please make sure that 
you recompiled back and all themes and what ever else you load into your 
application?
