If you're viewing an unfiltered bounty listing in someone's profile[jeff] the header N bounties isn't capitalized, though every other profile section header is.
I think the actual problem is that the unfiltered bounty listing isn't supposed to be displayed. Once you select a filter (active, offered or earned) there seems to be no way to clear it and return to the unfiltered listing. It also doesn't really make sense to throw offered and earned bounties in together.
edit: This doesn't use the header in question, but you can get the unsorted bounty list with a variety of other headers by using different
sort values in the query string:
&sort=votesuses Votes bounties.
&sort=activityuses Activity bounties.
&sort=newestuses Newest bounties.
&sort=viewsuses Views bounties.
&sort=addeduses Added bounties.
&sort=postuses Post bounties.
&sort=timeuses Time bounties.
&sort=graphuses Graph bounties.
&sort=suggestionsuses Suggestions bounties.
&sort=reviewsuses Reviews bounties.
&sort=revisionsuses Revisions bounties.
&sort=commentsuses Comments bounties.
&sort=badgesuses Badges bounties.
&sort=postsuses Posts bounties.
&sort=acceptsuses Accepts bounties.
&sort=answersuses Answers bounties.
&sort=nameuses Name bounties.
&sort=recentuses Recent bounties.
&sort=classuses Class bounties.
&sort=alluses All bounties.
Nis any other integer, gives you N bounties.
sort=16is the same as
sort=17is the same as
sort=18is the same as
I guess the tabs share the same sort options, internally, but bounties are the only tab that also uses it for filtering and modifying the title and so is alone in having this bug.
