I had the same issue, recreating the a tab named widgets did not help - just showed an empty tab called "widgets". When naming the tab, I can not see any dropdown list as mentioned in the post above.
The post quoted below worked for me though, thanks for the tip!

Interestingly, if I press hold the desktop, it pops up the home screen chooser thing where you can set the number and position of home screens. Under that is an icon for Wallpapers, Widgets and Settings. Tapping the WIdgets icon, takes me to the Widgets screen where I can choose/edit/place widgets.
