I confirm this with proprietary nvidia driver on two x86_64 machines.
Dolphin is very slow, sometimes unresponsive, especially when browsing
through directories containing large (200+) number of  files.

kdelibs-4.4.1-9.fc12.x86_64
kdebase-workspace-4.4.1-2.fc12.x86_64
qt-4.6.2-8.fc12.x86_64

I think this is related to
https://bugs.kde.org/show_bug.cgi?id=216932

Can we backport the fix to 4.4.2?
