NSInvaludArgumentException issue

[Raymond Camden]

I'm getting this error when running appledoc on a set of code:

Oops, something went wrong...

When I increase the verbosity, I get this rightbefore (and I'm going to rename some stuff due to NDA-lameness):

Registering typedef block AdobeFooNetworkResponseCompletion...

Matched AdobeFooNetworkResponseProgress typedef block definition at line 55.

The code in question is the last line of the file:

typedef void(^AdobeFooNetworkResponseProgress)(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpected);

Which as far as I know looks fine to me.

Seems legit code to me too.

Craslog doesn't tell me much except it's trying to append nil string.
Running appledoc from its Xcode project and giving it the same file to
chew on should include debug symbols in crashlog.

Other than that keep in mind currently appledoc doesn't support blocks.
But should not crash either :)

I'll file a bug report. Any way to make appledoc continue past this error in the meantime?
