Premises:

• Crucible 2.6.4
• Perforce (P4 server: P4D/NTX86/2008.2/190934 (2009/03/05)

Steps to replicate:

1. Create a new review.
2. Add a changeset ("rev8") with a single filename.cpp file to the review;
3. Add another changeset with a later revision ("rev9") of the same filename.cpp file to the same review;
4. The review's files list (on the left) shows filename.cpp twice, once for each changeset, one below the other.
5. When clicking each instance of filename.cpp, the revisions slider shows only two revisions being diffed:
   1. rev7 - rev8 for the first instance
   2. rev8 - rev9 for the second instance

This behavior is wrong, because only one file should be listed on the files list, and the revisions slider should display all the three revisions, i.e., rev7 - rev8 - rev9.

This happens to all browsers (FF 5, IE 9, Chrome).
No errors thrown in the logs.
