Index exceeds the number of array elements (0)

Hi folks,

there is this old GUI made with GUIDE which I try to export with Matlab Compiler. If I launch the application from Matlab, everything works fine, but if I try to launch the compiled app, this error occurs:

Index exceeds the number of array elements (0). Error in => xyz.m line 78

This part of code is generated automatically by Matlab and not written by me (auto generated initialization code):

...
else
    gui_mainfcn(gui_State, varargin{:}); %%in this line the error occurs
end
% End initialization code - DO NOT EDIT

I don't know how to fix this... it would be a pleasure to get any help.
