Thank you for the detailed explanation Andrea. I'll be looking forward to 4.6 RC2 then. For those who wonder, RC2 is 
planned - http://techbase.kde.org/Schedules/KDE4/4.6_Release_Schedule - to be released on Wednesday 5 January.

Like Shane I also noticed that GMail doesn't load, unless I choose the simple HTML interface. Is that issue also related to 
the KIO bugs, or does it have a different cause?
