This bug seems to be a result of the fix of Bug 13978 (Reverting to a flagged revision should automatically mark the resulting revision as flagged, too).
In the following situation, changes to templates get autoflagged without anyone checking them:
- article with latest flagged version exist, but it has a template that needs to be flagged
- Vandal does nasty edit
- Edit gets reverted and revert edit autoflagged because article was flagged at 1.
A picture is worth a thousand words:

I propose not to pay too much attention to this bug; a real management of flaggedrevs on templates is needed (imho). This bug report is just for your information.
