3 showstopper bugs for 4.7 release

[Marco Martin]

Hi all,

i just notice in my master build 3 rather serious bugs that really need to be 
fixed prior 4.7 release since they are pretty bad regressions, first step i 
would like if anybody else experiences those or are just evil wood elves in my 
setup:

* notification icon in the systray disappearing: sometimes it disappears from 
the systray and is not even available from the widget explorer as well

* menacing warning messages: load the microblog palsmoid (plasmoidviewer 
twitter) log in to identica and a warning message should appear (and that's 
the problem)

* taskbar screw ups: after opening and closing many windows, there are empty 
spots in the taskbar, so probably something dangling from libtaskmanager 

if somebody experiences those problems or has an idea how to fix them please 
tell.

i'll probably start to bisect around to see when broke

Cheers,
Marco Martin
