Its a fucking disaster. I used to blame kmail2 but came to realise its a decent frontend, its the back end that drags it down.
4.8 RC2 Gmail imap account, working fine for weeks. Nothing changed, then I get that perpetual rotating wait icon, followed by the
"Unable to fetch job" error when trying to access sub folders. Reboots don't make any difference.
I know the deal - the only reliable way to fix it is to delete the virtuoso/nepomuk databases and all kmail configs and recreate the account from scratch, but you know what? I just can't be bothered any more. Tired out and fed up. I've been a good boy, I given up hoping for a search that works, I don't attempt to integrate with google calendar or contacts any more, I don't expect address expansion to work reliably. Theres bug entries ate bugs.kde.org related to this months old with no dev attention, not even to confirm or reject then.
Its just easier to use my webmail or Thunderbird. At least it always works, even if its not as integrated with the kde desktop.
So one less reason to use KDE at all.
