Comment 2 for bug 412157

This happens because I have a /usr/share/color/icc directory looking like this:

andy@bloomfield:/usr/share/color/icc$ ls -al
total 6400

That's not likely to happen on most PCs, but I do it because of case sensitivity. This patch should fix the problem.

However, I do wonder if the issue is deeper in Mono. Maybe that file enumeration function shouldn't even return symlinks if they are duplicates?

I'm subscribing ubuntu-main-sponsors because I believe this is a perfectly valid fix for the issue for now.
