when I launch akonadiconsole from command line, no window appears but on ps akonadiconsole is at 100% cpu
(Interesting enough, kmail has exactly the same behaviour: nothing shows up, but 100% cpu used)
I've tried the same from a newly created account, same behaviour as well.
tried to use internal mysql and external mysql, no changes.
with dbus-launch akonadiconsole the behaviour is the same but i get some messages:

Nepomuk is alive, according to configuration and ps


Basically, it seems that something prevents windows to show up, while the correspondign process is running at 100%.
So far I noticed this for akonadiconsole and kmail
