Comment 1 Frank Reininghaus 2010-05-02 09:44:19 UTC 
Thanks for the bug report! This crash looks like it's related to Nepomuk. It gets reported quite frequently these days, but it seems that it only occurs on Kubuntu 10.04. Unfortunately, we don't know yet what the root cause of the bug is.

A temporary workaround for people who are annoyed by these frequent crashes might be to disable Nepomuk in the System Settings.

Comment 12 Sebastian Trueg 2010-05-04 11:42:49 UTC 
Can someone please install debug information for soprano and produce a backtrace with that.
Comment 13 Rahul Mehta 2010-05-04 11:49:40 UTC 
I think I've done that here:

Oh no sorry, my bad. I'm new to debugging basics.

Comment 16 Frank Reininghaus 2010-05-04 11:56:56 UTC 
@Sebastian: bug 234994 which looks quite similar is about a segfault in Soprano::Error::ErrorCache::clearError(), but that report (and it's duplicates) is also missing some Soprano debug info :-(
Comment 17 Rahul Mehta 2010-05-04 11:58:27 UTC 
Why does the automatic crash reporting system not install the required
soprano debug libraries automatically?
Comment 18 Frank Reininghaus 2010-05-04 12:04:23 UTC 
On Kubuntu, the command to install the required Soprano debug info package is

sudo apt-get install libsoprano-dbg

You can also install it via KPackageKit - just enter "soprano" in the text box and select the "debugging symbols..." entry.

Comment 20 Rahul Mehta 2010-05-04 12:08:04 UTC 
Thank you. I have installed the debug package and I will send the crash info
when it happens again.

Comment 34 Frank Reininghaus 2010-05-19 14:53:04 UTC 
To everyone who suffers greatly from this bug: A user provided some analysis in the related bug 234799. It seems that there might be two possible workarounds for this issue: Disable tool tips in the Dolpin settings ("General" section) or disable Nepomuk in the System Settings ("Advanced" tab/"Desktop Search").

The cause of the crash is still unknown - it looks like a memory corruption problem that is quite difficult to debug :-(

Comment 110 Charles MacDonald 2010-10-01 00:47:35 UTC 
Perhaps slightly different crash - Use Dolphin to start edit of a text file, Minimise dolphin.  When I come back, after saving the file find dolphin has crashed, The bug tool says my backtrace is probly not useful, but can't find the debug package.  I installed manualy the sudo apt-get install libsoprano-dbg pagage and tried to reload but it still said it was not useful

This is a core Duo machine if that would have any effect, long time since I tried to do any programming.

> Perhaps slightly different crash

This is bug 226725. Please do not add comments to long bug reports like this one unless you are really sure you have the same bug and you can add something useful. Everything else just causes lots of unnecessary mail for everyone and makes the report a lot harder to read. Thanks.

Dolphin sometimes crashes on startup on Mandriva 2010.1 x64. I'm fully up to date with official sources (Dolphin 1.4 on KDE 4.4.3). I have been unable to find a method to reproduce this consistently.

Just adding that I'm seeing quite similar issues on Kubuntu 10.10 (KDE 4.5.1), i.e. Dolphin, file dialogs, Gwenview, etc. are extremely slow to respond (or simply never open).  This behavior seems to be mitigated somewhat by fiddling with Window Decorations/themes, turning off file "previews" and the information pane in Dolphin windows, and most especially unchecking "Enable Nepomuk Semantic Desktop" in System Settings->Desktop Search.

Can this still be reproduced with KDE 4.5.5 or 4.6rc2?

Not sure that I sure comment here to you about this ... but will, my machine has 8G and a large swap and cache so I saw no reason to jack up the memory available to the process. That turned against me increasing cpu load (dual core AMD) and was reduced to 128MB where it sits now. I try to remember to turn off indexing when moving files. I've been reorganizing libraries that are on NTFS platters available to Samba. Recently while moving some PDF's, (ext4fs) after the move the folder was placed in Trash ... no accounting for good taste I guess ... I have also taken the NTFS platters off the indexing assignment for the time being. I'm not sure if the acl's on the NTFS platters have a hand in this or not. One last point in the matter, when using the "Alt+F2" kio to find material the list can be propagated with a number of similar but none descriptive file names ... proof of chaos right there.

For me on Dell 1764 i5 and 10.10, problem has disappeared.  Also running virtual kernel in VMWare Desktop without problems.  I a dropping for notification list as I have nothing of value to add.  Thanks to all who helped get fix in place for 10.10.

dolphin (1.6.1) on KDE Platform 4.6.1 (4.6.1) using Qt 4.7.2

- What I was doing when the application crashed:

I opened Dolphin, and in my Home dir I couldn't see any folder (Desktop, Documents, etc.), so I hit F5, which showed them all for a second, before crashing.

Comment 140 Lilian A. Moraru 2012-01-31 16:44:38 UTC 
Ye, I had a lot of crashes because of Nepomuk on Kubuntu, but since KDE 4.7 and Kubuntu 11.10 I had none. You should really try to upgrade to KDE 4.8 or newer guys.
Comment 141 Christoph Feck 2012-03-15 21:19:37 UTC 
No reports for KDE 4.7 or KDE 4.8, fixed in Nepomuk.
