Yes. I compiled Kernel 126.96.36.199 and upgrade my KDE 4.3.3 with txz.
1) why don't you use the build script from Slackware's sources for dbus?
I have problem with my X. I start X, it disables my mouse and keyboard.
This happened after I installed dbus. I received this message:
(**) ModulePath set to "/usr/lib/xorg/modules"
(WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.
(WW) Disabling Mouse0
(WW) Disabling Keyboard0
then I edited xorg.conf and put this code:
Option "AllowEmptyInput" "off"
Option "AutoAddDevices" "off"
my mouse and keyboard now works. I don't remember more. I guess was mono,
lMule, motif, wxWindows. I'm not sure. I was very busy with dbus during
two or three weeks, I forgot. I don't know now. But I needed upgrade my
dbus(1.3.0). I didn't find dbus on repository. I found 1.2.4. I promise
I'll talk to you later.
2) why did you feel the need to upgrade dbus anyway?
I promise I'll talk to you later. I don't remember
