The root cause for this is an issue in libdbus (see https://bugs.freedesktop.org/show_bug.cgi?id=17754 for details). The issue has sideeffects not only to Dolphin, but also on other parts of KDE (e. g. Nepomuk). However it gets triggered very often in Dolphin, as since KDE 4.5 Dolphin also retrieves metadata for files if Nepomuk is disabled.

The dbus-issue has been fixed in the meantime, but AFAIK it has not been backported to the stable release branch. Until then the only workaround to bypass those hangs is to disable the Information Panel and/or tooltips in Dolphin.

I'm quite frustrated about this issue myself and of course thought about providing workarounds to bypass this issue, but those workarounds would result in new issues...

There is a reason why your distro doesn't carry still KDE 4.5 by default. Check your DBus package. If it's 1.2.2x, you'll certainly have delays. If you run 1.3.1, you are saved from all delays. Wait a little bit... the major distro refresh is not too far.

If you run Ubuntu, add this PPA and follow the instructions in this page.

If you run Fedora, DOWNLOAD THIS SOURCE RPM
http://koji.fedoraproject.org/koji/buil ... dID=179429
After that, recompile it with rpmbuild --rebuild.
DO NOT DOWNLOAD A NEWER RELEASE (unless you really want to switch to Fedora 14, the dbus 1.3.2-snapshot there has support for SystemD)

If you run Arch Linux, then install this package from AUR
http://aur.archlinux.org/packages.php?ID=37728
This is dbus 1.2.24 with the race condition bugfix patched in. It will work great, but can break another apps, so beware.

After that, your KDE will be snappy.
