[viewvc-users] Only *some* diffs give exception on Windows

I have:
CollabNetSubversion-server-1.6.2-1.win32 - Apache, not svnsvr
python-2.5.4
pywin32-213.win32-py2.5
diffutils-2.8.7-1 - installed at C:\GnuWin32\bin and in PATH

When I am at a page like this:
http://<ipaddr>/viewvc/repository/trunk/proj/ExampleFile1.txt?view=log

and I click "Diff to previous XX", *some* links take me to a successful Colored Diff page, while others give me the exception below. 
When a link fails, I can successfully diff each of the 2 revisions involved in the failed link against different revisions, so I don't think either revision is corrupt.

For example, a link that fails is:
http://<ipaddr>/viewvc/repository/trunk/proj/ExampleFile1.txt?r1=21&r2=22
but these succeed:
...r1=20&r2=21
...r1=22&r2=23
...r1=23&r2=22
...r1=21&r2=20

Interestingly, if I change the url by hand to swap the order of the revisions in the offending link, the swap-ordered link works. Following my previous example:
...r1=22&r2=21
is OK.

I thought the exception below is typically the result of python not being able to find "diff" in the PATH, but why do *some* of my links diff properly?

Any thoughts?

Thank you,
Jeff Hoover
