Update information - KDE service (black frame?)

[timonoj]

Hi guys,

A couple of days ago a lightbulb icon showed up on my tray. It says something about an available update (but it's not the standard system updates, with the gears, just a lightbulb). When I click, a black horizontal rectangle occupies both of my screens. That's the window, and I can't see any content in it. The window details (on the task bar) shows only "Update information - KDE service". Since it's an update, I'll have it popping in every single time I reboot. What is this? How can I make the window visible/authorize the update?

EDIT: In the system activities panel (control+esc), it is listed as kded4, or kdeinit4.

Thank you!
