In the Revision history there are radio buttons for selecting the versions for diffing. They are supposed to be vertically aligned. When the "Justify paragraphs" option is enabled in the preferences they may move and break the alignment. A simple way to solve it would be not to use paragraph justification for the revision history page at all.
Also consider Bug #20184 when fixing this.
Can you attach please a screenshot of this?

The preference was just recently removed (bug 52810), I guess that makes this a WONTFIX.
