After using the MATLAB 6.5 (R13) Editor and then exiting, why do subsequent MATLAB launches fail?

I launch MATLAB 6.5 (R13) for Linux and use the MATLAB Editor. If I leave the Editor open and exit MATLAB, subsequent launches of MATLAB cause the following error log file, and MATLAB does not start anymore:

 An unexpected exception has been detected in native code outside the VM.

 Unexpected Signal : 11 occurred at PC=0x4113dc6e

This is a bug in MATLAB 6.5 (R13) that our development staff is investigating for a future release of MATLAB.

This issue may have been caused by exiting MATLAB before exiting the MATLAB Editor.

There are a couple possible workarounds.

1) First, to recover MATLAB and be able to start it again, you will need to exit MATLAB and delete or rename the ~/.matlab/R13/ directory, which will remove all of your preferences. Please remember to exit the Editor before exiting MATLAB in subsequent sessions.

2) Alternatively, if you launch MATLAB without the desktop (matlab -nodesktop) and then subsequently execute the "desktop" command at the MATLAB prompt, the error will not occur. You may want to consider putting the "desktop" command into a "startup.m" file on your MATLAB path, and also change the alias to MATLAB so that it launches with the -nodesktop flag.
