If the bug is reproducible for anyone, it would really help if we could get a backtrace with full Soprano debugging information (the crash seems to be related to Nepomuk/Soprano). To install the required package on Kubuntu enter sudo apt-get install libsoprano-dbg in a Konsole. You can also install it via KPackageKit - just enter "soprano" in the text box and select the "debugging symbols..." entry. If you see this crash again, please paste the new backtrace here. Thanks!

Alright, package installed. Should the crash occur again, I'll follow your instructions. Many thanks.

@Leonardo: could you please explain what you were doing when the crash occurred? Did you run Dolphin as root, too? Is your Nepomuk setup working properly?

Is your Nepomuk setup working > properly? Hi, sure. Today, no, I wasn't running Dolphin with superuser privileges. I had just dropped a folder containing a dozen mp3s from an external HD (where all the downloads end) to another (containing Amarok local collection), both formatted with EXT4 file system. I can't remember if I hit on the first HD tab to return to it, or if the crash occurred as soon as the file transfer completed. As for Nepomuk, I honestly don't use it much (once or twice I tried the search function within Dolphin out of curiosity), for its scope is still largely unclear to me, although I've read extensively about it. Also, its icon sits in the system tray, and the application configuration is properly set to its default values, so I haven't customised it in anyway. I hope that helps.

Created attachment 43583 [details] New crash information added by DrKonqi I believe I am suffering from this same bug. Dolphin crashes randomly, it seems related to clicking on things or performing actions within Dolphin. I have disabled previewing and the problem persists. At times it makes Dolphin entirely unuseable. I have only tried with Dolphin running under a standard user. The QuickAccess Plasmoid does not suffer from this problem. I have not customized nepomuk/soprano, although I tried turning off File Indexing to see if it helped. It appeared to at first but is crashing just as often now. (I cannot replicate the problem under Gentoo with the same versions)

First, I'm just a simple user. Second, can you please try again with the new Dolphin 2 in KDE 4.8?
I'm closing this bug now: The crash from the original reporter cannot occur anymore in Dolphin 4.8 (parsing of metadata is done in a custom process, so even a crash there would not crash Dolphin).
