Comment (by KirkM):

 I'm hoping this is the correct place for this. In my testing I've found a
 problem with the current Media Library. It seems to have been around for
 the last few revisions. I've compared two different test sites below that
 exhibit the same problem.

 In the "Manage/MediaLibrary", when selecting any link in the "Media"
 column brings up the selected image's edit page as usual. At that point
 "Settings",
 "Plugins" and "Users" disappears from the top right of page and the
 following warning is displayed at the bottom of the page:

 Warning*: Cannot modify header information - headers already sent by
 (output started at
 /home/longmead/public_html/just-thinkin/wp-admin/admin-header.php:26) in
 */home/longmead/public_html/just-thinkin/wp-includes/pluggable.php* on
 line *688

 All plugins are deactivated during this test.

 On my other test site currently running on r2998 the same thing occurs
 with the exception of slight change in the warning (different line #):

 *Warning*: Cannot modify header information - headers already sent by
 (output started at
 /home/longmead/public_html/just-thinkin/wp25-test/wp-admin/admin-
 header.php:26)
 in
 */home/longmead/public_html/just-thinkin/wp25-test/wp-
 includes/pluggable.php*
 on line *687

 Again, no plugins activated.

 I'm to light yet on the ins and outs of the Wordpress code to troubleshoot
 this myself.
