Version: (using Devel) Compiler: gcc-4.3.4 OS: Linux Installed from: Compiled sources When triggering an action (entering a folder, erasing a file, launching a file (photo, video...)... etc) Dolphin often freezes for almost a minute. The wierd thing is: launching a new Dolphin window unfreezes it.
Got a console log when that happens : "/home/loacoon/Program-Files/KDE4/bin/dolphin(2970)" Error in thread 2969779056 : "org.freedesktop.DBus.Error.ServiceUnknown - The name org.kde.nepomuk.services.nepomukstorage was not provided by any .service files" "/home/loacoon/Program-Files/KDE4/bin/dolphin(2970)" Error in thread 2969779056 : "Unsupported operation (2)": "Invalid model" "/home/loacoon/Program-Files/KDE4/bin/dolphin(2970)" Error in thread 2969779056 : "org.freedesktop.DBus.Error.ServiceUnknown - The name org.kde.nepomuk.services.nepomukstorage was not provided by any .service files" "/home/loacoon/Program-Files/KDE4/bin/dolphin(2970)" Error in thread 2969779056 : "Unsupported operation (2)": "Invalid model" "/home/loacoon/Program-Files/KDE4/bin/dolphin(2970)" Error in thread 2969779056 : "Unsupported operation (2)": "Invalid model" "/home/loacoon/Program-Files/KDE4/bin/dolphin(2970)" Error in thread 2969779056 : "Invalid iterator."

It seems to be related with Nepomuk, but it still happens when disabling it.
Same here in Kubuntu with KDE 4.5 beta2, how to debug this issue?
I confirm that those random freezes are also present in KDE 4.5RC1. For example if I'm working in kate and switch back to Dolphin, it takes a few seconds before it actually goes into the folder I clicked. The folders I browse are not large (< 20 subfiles/folders).
I have the same problem with KDE 4.5.0 from Kubuntu PPA. It also happens when I click (single selection click) on some PDF files. I tried to deactivate previews but it didn't changed anything. But dolphin unfreeze itself after about 5 seconds but that delay vary every time. Nepomuk is deactivated for me too. This bug happens to me, approximatively, 40% of every time I click on something in Dolphin.
It seems like deactivating Strigi/Nepomuk has no effect on Dolphin (still having Strigi related crashes and Nepomuk related errors). So this may be related to our problem...
Other thing, I have the information panel (with the icon, owner, permissions, ...) opened (embedded) within Dolphin. Maybe it's related? I also read something about DBus on other bugs. My version of DBus is "D-Bus Message Bus Daemon 1.2.16".
Christoph Feck just confirmed on bug 232054, that updating to dbus 1.3.2 + 4.5.0 solves this issue (see comment #55). *** This bug has been marked as a duplicate of bug 232054 ***
