Version: 1.1.80 (KDE 4.1.96) (using Devel) OS: Linux Installed from: Compiled sources I'm having various ext3, XFS and NTFS partitions on a second hard disk drive that are not automounted on startup but automagically recognised by Dolphin. When I click on one of these drives in the Locations sidebar, I should be asked for the root password. Before the sudo dialog opens, Dolphin crashes with SIGABRT (see backtrace 1). Now, I can enter the password and start Dolphin again with the partition being mounted and accessible without further crash. Clicking on another unmounted partition should mount it (without asking for the password again). However, Dolphin crashes again (see backtrace 2) and I need to restart again to have the second partition mounted and accessible. This will happen with every single unmounted partition but not with removable devices like a USB stick. This crash occurs every single time (100% reproduceable) since I'm using KDE 4.2 Beta or RC. I believe the crash occured only sometimes with KDE 4.1, but I'm not sure - I might have got used to the crash... =============== Backtrace 1: (crash on first mount requiring the password) ------------------ Anwendung: Dolphin (dolphin), Signal SIGABRT 0x00007f3ec3b2c621 in nanosleep () from /lib/libc.so.6 [Current thread is 0 (LWP 9383)] Thread 3 (Thread 0x4112a950 (LWP 9440)): #0 0x00007f3ec3b63482 in select () from /lib/libc.so.6 #1 0x00007f3ec46d5006 in ??

This might be related to bug 178727
first backtrace resembles bug 180617, so the two bugs might be related
Thanks for the bug report! > This might be related to bug 178727 Bug 178727 is a different crash - looks like a Strigi issue. 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
This bug probably has a common cause with Bug 180765. However, I did separate backtraces for it: Starting "dolphin" from a Konsole as regular user (no sudo), everything works well, interestingly. However this is the command line output: dolphin(7938): Attempt to use QAction "close_tab" with KXMLGUIFactory! dolphin(7938): Attempt to use QAction "show_info_panel" with KXMLGUIFactory! dolphin(7938): Attempt to use QAction "show_folders_panel" with KXMLGUIFactory! dolphin(7938): Attempt to use QAction "show_terminal_panel" with KXMLGUIFactory! dolphin(7938): Attempt to use QAction "show_places_panel" with KXMLGUIFactory! dolphin(7938) MetaDataWidget::setFile: KUrl("file:///home/pancho") pancho@luka:~$ dolphin(7938) MetaDataWidget::setFile: KUrl("file:///home/pancho") dolphin(7938) MetaDataWidget::setFile: KUrl("file:///media/home") dolphin(7938) MetaDataWidget::setFile: KUrl("file:///media/Windows Vista") 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"
I also created a valgrind log (see also Bug 180765): 1. After a restart... 2. ... I ran "valgrind --log-file=180621a.log dolphin" 3. I clicked on the icon for /media/home (unmounted XFS partition) 4. kdesudo asked for my password, so I entered it 5. I clicked on the icon for /media/Windows Vista (unmounted NTFS partition) 6.

*** Bug 180765 has been marked as a duplicate of this bug. ***
Do not run "valgrind dolphin", dolphin forks on startup so you get nothing of interest in the log. Run "valgrind dolphin --nofork" instead please.
THe backtrace in comment 6 looks the same as the one in bug 178897 (I reported that and I can no longer reproduce it) This probably related/duplicate
Bernd, can you still reproduce the crash in 4.2.0? If not, it's probably really a duplicate of bug 178897, as Darío said.
Bernd, I'm closing this issue as it looks like a duplicate of bug 178897. Please reopen the issue if it still occurs with KDE 4.2.0 in your environment. Thanks!
