Look into the REDUCEVOLUME and SHRINKFACES functions.

Ewwwwww.  It crashes my computer too.  It seems to be 
having a problem with the large number of faces.  Using 
REDUCEVOLUME with the factors [4,4,2] allows setting an 
EdgeAlpha value without crashing.

I definately recommend reporting this crash directly to 
technical support (not the the segv@whatever email they 
give).  This has got to be a bug.

I didn't like how REDUCEVOLUME looked, but using 
SHRINKFACES with a very small number, for example:

shrinkfaces(h,0.01)

seemed to be able to retain some decent skull resolution.
