Navigate to a Bundle Version and you'll see the breadcrumbs looks something like this:
Bundles > Sample Bundle > Versions > 1.0 Versions > 1.0
Note the repeated portion offset to the right.
This did not appear on FF3.6.3.
Tested on JON 2.4 with IE 6/7/8 and FF3.0.19
The issue reproduced on IE-7. Please refer attached file for screenshot.
