Hi Robert,
I was discussing this issue with a Mac IT Admin and he emailed me the
following link:
http://www.adobe.com/support/techdocs/329299.html
It's an Adobe Tech Doc. It seems that Adobe apps have similar
issues. He stated that it could be when the Application (Acrobat
Reader?) was first installed and the font exist on a the Adobe CD.
Not really sure how "AdobeFnt06.lst" can add/affect the
"availableFonts".
Hope this helps.
Thanks,
John Nunez

A friend was testing an app for me and it crashed on his system at
start-up. The immediate problem was a piece of code like this:
NSArray* fontList = [[NSFontManager sharedFontManager]
availableFonts];
int fontCount = [fontList count];
for ( j=0; j < fontCount; j++ )
{
NSFont* font =
[NSFont fontWithName: [fontList objectAtIndex: j]
size: 18.0];
NSDictionary* fontStringAttributes =
[NSDictionary dictionaryWithObject: font
forKey:
NSFontAttributeName];
...
}
The problem is that font came back nil at some point and
[NSDictionary dictionaryWithObject: forKey] spit up and crashed
because it didn't like the nil.
OK - My fault for not checking for nil and easy to fix. But the
larger issue is why is NSFontManger telling me a font is available
when NSFont refuses to create an instance ?
On further investigation the guilty fonts are:
GloucesterMT-ExtraCondensed
and
AbadiMT-CondensedExtraBold
Looking in the usual font locations there are no font files of
these names nor does
find / -name "*GloucesterMT-ExtraCondensed*" -print > findResults,
etc show up any font files. A good reason not to create an instance.
A Spotlight search showed that those names appear in:
~Library/Application Support/Adobe/TypeSpt/AdobeFnt06.lst.
I don't know about AdobeFnt.lst files, but a little Googling shows
they seem to be the cause of lots of trouble. The friend is a math
type not a graphic arts type and says he didn't consciously install
those fonts.
