Hi,

I don't know whether this helps to track down the problem, but here goes 
anyway: I see the same crash with .ps and .eps files (unsurprisingly, as 
these and .pdf are processed by libgs). The same conversions work with 
"gm convert" from the GraphicsMagick package. gm is not linked against 
libgs, but seems to invoke the gs executable instead. This does not 
crash, although it is linked against the very same libgs.

regards,
Markus
