My sabayon is 4.1 kde x86_64.
I just upgraded to rev 1028, qt packages was updated to 4.5.1.
kdm version is 4.2.2-r2.
After that i restart, but kdm was not displayed.
From kdm.log, it display error message something like "kcrash:kdmgreeting crashed, due to incompatible qt library"
I just did another world upgrade, then it fetched qt-gui,qt-svg and qt-assistant.
Strange, my previous world upgrade change my revision to 1028.
It seem above qt packages were not installed.
Also my ktorrent upgraded to latest revision, but equo doesnot updated to 0.90.
