Since I upgraded to KDE 4.7 I have had connection problems with KMail2 and Choqok. Sometimes KMail2 can't connect to POP or SMTP accounts because of a timed out error: "pop/ Socket operation timed out". It only happens sometimes. Sometimes continuously and sometimes it just connects right when I click on the check for new mails button.
With Choqok it doesn't refresh my friends list on startup because of a timed out error again.

KMail2 socket error ss:

This never happens with KDE 4.6.

Thanks in advance!
