Hello,

I just installed Kmail 4.6 - beta3, and I'm facing some problems.
I can read the mails (imap..and a lot of mails in inbox, so the migration took ages), but when I send an e-mail , the mail keeps in 'sending' state. The window stays open, and grayed out.
On the system, the virtuoso-t process is going through the roof, consuming all CPU.
Any idea what the problem could be, and how I can solve this?

You have likely triggered the issue in Virtuoso which causes it to become inoperable. The only fix in this case is to logout, kill virtusoso-t, then login again and try once more.

That can be fixed also by preventing virtuoso to acccess the mail messages outside Kontact - this is done by opening up KRunner (alt-f2), configuring it (wrench icon) and unchecking "Nepomuk Search".
