Sorry for the delayed response: it took me a while to figure out how to build
this with all the proper dependencies.

Trunk made no difference (output below).  I put in a few Console.WriteLines in
Mime.CheckForBinaryOrText() to print the buffer.Length and the buffer contents,
as well as in Mime.GetMimeTypeForFile() to print the file whose mime-type is
being discovered:

> Getting mime type for /Users/bsd/Downloads/MoMA/ICSharpCode.SharpZipLib.dll
> buffer has 0 bytes: System.Byte[]

Putting a check in Mime.CheckForBinaryOrText() to check the buffer length
prevents this bug and MoMA completes successfully.

-                       for (int i = 0; i < 32; i++) {
+                       for (int i = 0; i < 32 && i < buffer.Length; i++) {


------------------------------------
Getting mime type for /Users/bsd/Downloads/MoMA/ICSharpCode.SharpZipLib.dll
buffer has 0 bytes: System.Byte[]

Unhandled Exception: System.IndexOutOfRangeException: Array index is out of
range.
