Thanks for the bug report! Looks similar to your bug 180621 and a couple of others, but to be sure and to find the root cause of the crash, more information would be helpful (I'm not running Kubuntu Intrepid and can't reproduce the crash at the moment). It might help if you could run Dolphin from a Konsole and paste the "ASSERT...." line from the output during the crash here (if there is one) or - even better - provide a more detailed backtrace, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Thanks!
Yes, I also think this and bug 180621 have a common cause, obviously the crash happens when superuser privileges are requested, which happens in both cases. Interestingly, when starting "dolphin" from a Konsole (as regular user w/o sudo), everything works fine without a crash. However, the command line output is: pancho@luka:~$ dolphin(7359): Attempt to use QAction "close_tab" with KXMLGUIFactory! dolphin(7359): Attempt to use QAction "show_info_panel" with KXMLGUIFactory! dolphin(7359): Attempt to use QAction "show_folders_panel" with KXMLGUIFactory! dolphin(7359): Attempt to use QAction "show_terminal_panel" with KXMLGUIFactory! dolphin(7359): Attempt to use QAction "show_places_panel" with KXMLGUIFactory! dolphin(7359) MetaDataWidget::setFile: KUrl("file:///home/pancho") dolphin(7359) MetaDataWidget::setFile: KUrl("file:///home/pancho") kDebugStream called after destruction (from void KDirWatchPrivate::removeEntry(KDirWatch*, KDirWatchPrivate::Entry*, KDirWatchPrivate::Entry*) file /build/buildd/kde4libs-4.1.96/kio/kio/kdirwatch.cpp line 836) Cancelled INotify (fd 25, 1) for "/home/pancho/.local/share"
With a more detailed backtrace I guessed you meant a valgrind log, so here are two of them: For the first one, after a restart I ran "valgrind --log-file=180621.log dolphin", but didn't do anything in Dolphin (just quit after it has started). ==7666== Memcheck, a memory error detector. ==7666== Copyright (C) 2002-2007, and GNU GPL'd, by Julian Seward et al. ==7666== Using LibVEX rev 1854, a library for dynamic binary translation. ==7666== Copyright (C) 2004-2007, and GNU GPL'd, by OpenWorks LLP. ==7666== Using valgrind-3.3.1-Debian, a dynamic binary instrumentation framework. ==7666== Copyright (C) 2000-2007, and GNU GPL'd, by Julian Seward et al. ==7666== For more details, rerun with: -v ==7666== ==7666== My PID = 7666, parent PID = 6890.

Thanks for the update! The Konsole output and the Valgrind log seem to be unrelated to the crash, but that was to be expected because you did not get a crash by running Dolphin from a Konsole. One more helpful thing you could do would be installing debugging packages. I would guess that 'sudo apt-get install kdelibs5-dbg kdebase-dbg' is the command required to do that. If you reproduce the crash then and get a backtrace (like you did in the original report), this will add more information to the '?? ()' lines and also line number information which could give a hint to the root cause of the bug.
I'm reassigning this to KIO because the backtrace from the original report indicates that it might be a KIO issue. David: note that bug 180740, bug 180621, and bug 180562, apparently all reported for 4.2-development versions, have the same (incomplete) backtrace. The backtrace also resembles bug 168478 which is fixed since 4.1.3 (and which I still can't reproduce in trunk rev. 911116).
Please add --nofork after "dolphin" when running valgrind.
With identical backtraces, this is obviously essentially the same bug as bug 180621, so I'm marking this as duplicate. *** This bug has been marked as a duplicate of bug 180621 ***
