That gives me "Latin Modern Roman Slanted".  But:

(gdb) print-object families
{(
    Helvetica,
    Cochin,
    Code2000,
    Geneva,
    "Hoefler Text",
    "Arial Unicode MS"
)}

so that seems to indicate that it worked OK for 6 of them.

The missing charsets are:

2009-05-31 10:40:36.018 Emacs[81083:813] No charset for family: Latin  
Modern Roman Slanted
2009-05-31 10:40:36.411 Emacs[81083:813] No charset for family: Snell  
Roundhand

I've put in a condition to avoid adding the font if there is no charset.

Now we've got another crash:
