crash due to MEX file? but i'm not using MEX!

I tried executing a script that uses the Image Processing toolbox on R2010a on Macbook Pro running OS 10.5. This script runs fine on other computers but for some reason, it causes this particular installation to crash with the following error report. It complains of a problem with a MEX file but my script does not call MEX files as far as I know. Does anyone have any idea what's going on?

Thanks, Angi

It appears that there is a problem with Mathwork's implementation of imerode() on a logical matrix .

Although you are not using mex, Mathworks is.

Please report the problem to Mathworks support.

Thanks! I'll send them a bug report then.
