GUI Alt+Tab Crash

I have a GUI (built by someone else) that has a problem when I try to Alt+Tab to another program - the program crashes on a MATLAB built-in function. I have built the GUI into an executable, and the executable (GUI) will crash in the same way. I would like to be able to switch to another program/screen using Alt+Tab without crashing the GUI.

This is in Linux, with MATLAB 2010a.

How can we help you? I assume you are the only one who can figure out, where the program is crashing. And it will be useful to explain "crashing" with any details.
