KDE SC 4.10's KMail acting very weird
So I'm running Slackware64 14.0 and have been upgrading KDE using AlienBob's packages, that of which I'm thankful for. I've gone from 4.8.5 -> 4.9.3 -> 4.9.4 -> 4.9.5 and to finally 4.10.0. Haven't really hit any problems from all these upgrades until 4.10.0 where KMail won't retrieve any e-mails from two of my IMAP servers. I've tried removing those two accounts and adding them back in... it connects, but refuses to retrieve the messages. I've also moved everything from my home directory elsewhere, effectively giving my user account a fresh KDE configuration, but KMail still does the same thing. I've rebooted my machine, removed everything from /tmp, /var/tmp/kde*, and also reinstalled the KDE packages with no change in outcome. I would rather not wipe my system and re-install to resolve this as that is kind of a crappy way to solve an issue, but I also don't want to spend so much time that re-installing would be more feasible so I'm looking for some suggestions.
I have verified that it's definitely something on my system by installing KDE 4.10.0 under virtual instances KUbuntu AND Slackware64 14.0 and they work fine. I can also telnet to the IMAP server with no problems... so any suggestions would be welcome!
