Description of problem:
Almost always when I alt-tab from Firefox to Konsole, it does not accept any keyboard input at all. Workaround is to use mouse to switch to different tab (and back) or to another window first. It only happens form Firefox to Konsole, and only if I use alt+tab (not when I use mouse to switch from the panel.

Version-Release number of selected component (if applicable):
*Mozilla/5.0 (X11; U; Linux x86_64; fi-FI; rv:1.9.1.9) Gecko/20100330 Fedora/3.5.9-2.fc12 Firefox/3.5.9
*Konsole, Versio 2.4.2, Käytetään KDE:n kehitysalustaa 4.4.2 (KDE 4.4.2)

How reproducible:
Very.

Steps to Reproduce:
1. Start Firefox
2. Start Konsole
3. Alt+tab from Firefox to Konsole few times and try to write into Konsole

Additional info:
Problem goes away if I kill imsettings-daemon (which uses ibus), and comes back if I start it again.
