I think these photos will explain better

1- First we open Add Widgets Dialog :

2- Then selected any of plasmoid from list
http://imaj.at/45868.jpg


3- Then clicked to searchAreaTextbar and typed f.
And ALL graphics gone :

4-Then deleted that f which we wrote and all list's graphics gone :
http://imaj.at/45870.jpg


The console kdebug output is ( when typing f in searchareatext ) :

plasma(12515)/libplasma KCategorizedItemsView::searchTermChanged: EVENT

You can reproduce that bug with also clicking scrollbar instead of selecting
any of plasmoid before writing anything into searchtextarea
