Qt Version: 4.8.2
Operating System: Linux 3.4.6-1-ARCH x86_64

- What I was doing when the application crashed:

Manually started dolphin via the terminal. I was planning on debugging some Nepomuk stuff, however Nepmuk was not running. I'm attaching the debug output from dolphin -

Comment 1 Frank Reininghaus 2012-08-03 06:20:58 UTC
Thanks for the bug report! It looks like the Information Panel has trouble with one of the files in the folder you're trying to open. It might help if you could isolate this file.
Comment 2 Vishesh Handa 2012-08-03 07:16:33 UTC
Damn. After restarting Nepomuk I can't seem to reproduce this. It might even be cause I was running a couple of mock dbus sessions for testing.

Even thought the backtrace says that. I'm not convinced that it could be cause of any file - well no problem cause of Nepomuk or strigi. That's because the KFileMetadataWidget runs the metadata fetcher in another process.

Also, the backtrace seem a little corrupted -

Missing  - bool Factory::isMimeTypeAvailable(const QString &mimeType)

See - slotFolderStatFinished - nothing to do with files.

Anyway, the crash seems to be in -     
const KService::List offers = KServiceTypeTrader::self()->query("PhononBackend",
            "Type == 'Service' and [X-KDE-PhononBackendInfo-InterfaceVersion] == 1");

This doesn't really seem like a dolphin bug. I'm not sure what to reassign this bug to. Any suggestions?

Sorry, no idea! Maybe dfaure might know.
