I went to Oslo for a weekend, and during that time I turned off roaming. Which meant, that every time synchronization hit - it kept asking me if I wanted to go online and I kept saying "no!" (and cancel on the password dialog).

Since that time, I have to enter all my passwords after rebooting and Twitter appears to be the worst - asking me every time the program is closed.

I have tried removing accounts and adding them again - I also did a "restore settings" from the settings menu, rebooted and added everything again.

I even tried removing the accounts.db, verifying it on my Linux PC and can't find anything wrong with it.
