Upgrade causes Topic Revision string to break

When I upgraded all my plugins recently I noticed that at the bottom of each page on my wiki install the Topic revision: line had not rendered properly. It would appear in the browser something like this:

 Topic revision: r2 - 11 Jul 2012 $percntIF{$quotistopic '%USERSWEB%.$wikiname'$quot then=$quot[[%USERSWEB%.$wikiname][$wikiname]]$quot else=$quot!$wikiname$quot}$percnt"}

After much digging I tracked the problem down to a change (at r14243 2012-03-08) in view.pattern.tmpl, which is part of PatternSkin. The change was to a macro called REVINFO. Surprisingly, the same change had been made at the top of the page after the breadcrumbs and worked fine there. I eventually "fixed" the problem by changing the suspect instance of REVINFO back to one without arguments. For me, the rendered result is better anyway. Not sure what the root cause is though.

Sure enough, everything worked fine when I upgraded to foswiki 1.1.5.

I've finally learnt my lesson (took a couple of goes) - never upgrade plugins when there is a newer version of foswiki available.
