Note that KDE on Ubuntu has historically been fucked up.
I've had much better experience on OpenSuse.
(not sure why, but a lot of KDE people hate Kubuntu for
giving KDE bad credit)
I'm currently using Kubuntu 11.10 with KDE 4.7 though, and haven't
encountered any bugs - except social desktop, which I disabled
(Kubuntu/KDE4.6 wasn't usable - OpenSuse was)
That said, KDE 4.8 is going to be released in 2 days, and it's
mostly
bugfixes and optimizations. So if you try KDE4 again, I recommend
waiting
for the next round of distros with 4.8 .
KDE plans for 4.9 is also bugfixes, while 5.0 (don't panic)
should be a refactor
without breaking user interface - but they plan to clean up the
APIs (as opposed to 4.0 - where they rewrote everything from
scratch).
I'm not sure if Trinity has enough devs to do anything but
maintain KDE3 comptatibility - MATE seems more promising to me (I
liked Gnome 2 even though
I'm converted to KDE now).
