Comment (by Brianglanz):

 I've seen this one; it must not be #27897 exactly.

 I had let the auto upgrade run, 3.9 to 3.9.1 on a network of 36 sites. I
 checked in and all appeared to be fine. Then, I noticed a typo in a
 widget, on the main or root site. I logged in to correct it, went straight
 to /wp-admin/widgets.php and on load, I found most widgets had been moved
 to Inactive Widgets.

 Again, the widgets were not misplaced until after I loaded widgets.php.
 I'm in a rush, so can only offer two more bits of info and no fix (sorry).

 1) The widgets were not all misplaced to Inactive, rather they were
 returned to a state I had previously saved while running 3.9. In that
 state, there were four widgets in use in the Main Sidebar and First Front
 Page Widget Area of a 2012 child theme. Those four widgets and their
 placement were preserved, while the six widgets I had more recently added
 were misplaced to Inactive. In the state which was partly lost, a few
 widgets were also in the Second Front Page Widget Area, but widgets were
 misplaced from all three sidebars in use.

 2) Thankfully, this only happened on the main site. I confirmed that all
 network sites were up to 3.9.1 so the automagic must also have run /wp-
 admin/network/upgrade.php (thank you). However, it might also be the case
 that none of the other sites had edited a widget since the state which was
 preserved, so this paragraph might not actually be additional info. BG
