Description Alvaro Manuel Recio Perez 2010-04-19 13:26:00 UTC 
Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
I recently have installed a KDE Service Menu (http://kde-apps.org/content/show.php/Attach+to+thunderbird?content=122832) while keeping several Dolphin windows opened. The service installed correctly and Dolphin showed the new entry in context menus.

Then, I edited the desktop file for that service menu to change the icon. Just after saving the changes and trying to see if the context menu showed the new icon, Dolphin crashed.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Thanks for the bug report! This crash looks related to Nepomuk. I think it might be a duplicate of bug 235166.

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 then, please paste the new backtrace here. Thanks!

Comment 22 Hans Reisner 2010-05-12 21:06:54 UTC 
Hello,

I've tested a little today and now deactivated nepomuk and strigi; since this I've had no crash of Dolphin. It crashed always on first startup and seemed to crash on mouse events like mouse over folder icon or file icon (???) Could it be, that there's a coherence between the services and Dolphin? Can anyone other replicate this behavior?

Thanks,
Hans
Comment 23 Frank Reininghaus 2010-05-13 14:28:25 UTC 
Hans, thanks for the update. The backtraces already indicated that the crash is indeed related to Nepomuk - that's why deactivating it stops the crashing. Note that this does not necessarily mean that the bug is in Nepomuk itself - it could be in any library that Dolphin uses. We don't know yet because we could not reproduce the crash so far.

There is a connection: When you move the mouse over an icon, Dolphin starts a Nepomuk thread that loads information about the file.

Hi Frank,

had someone tested how it reacts (? is this the right word ?) if Dolphin and Nepomuk try to use a file at the same time?

This is most likely not the problem. Some of the backtraces indicate that there is some kind of memory corruption which causes the crash.

Ok, Frank, 

> This is most likely not the problem. Some of the backtraces indicate that there
> is some kind of memory corruption which causes the crash.

I've got some news, so maybe you can reproduce this:

- Select one folder with pictures (jpeg in my case)
- Set only this folder to be indexed by Nepomuk and Strigi
- Start dolphin in one window, system-settings in another (parallel)
- Start Nepomuk in system-settings and be fast to get the mouse over the pictures in dolphin
- With luck, dolphin crashes while loading the preview (on the right and the popup)


Here some output of dolphin --nofork, maybe it helps:

(In reply to comment #27)

Great Update: 

Now I found out, that Dolphin only crashes, if "Kurzinfos" (in german version, maybe it's called shortinfos or something) is activated; Dolphin not only crashes with pictures, it crashes also with "normal" files.

Little explanation: With "Kurzinfos" I mean the litte popup which contains infos about the file. It contains filename, filesize, preview and it is viewed if you "mouse over" a file.

I hope someone can now verify this bug.

Greez,
Hans

Sorry for this Ingrid; I could see that the crash happens at the same time Strigi started indexing files in this folder.

Greez,
Hans
Comment 31 Frank Reininghaus 2010-05-14 19:59:47 UTC 
Hans, thanks for your input, this was very helpful! I've enabled tool tips (that's the English name for "Kurzinfos") in my Kubuntu virtual machine and reproduced the crash just by hovering a couple of items with the mouse.

I'll try to get some more useful information out of it (might take a couple of days though because I'm a bit busy with real life issues this weekend).

Thanks again!
Comment 32 Frank Reininghaus 2010-05-16 17:15:51 UTC 
I've been able to reproduce the crash while running Dolphin in Valgrind. The interesting part of the log is shown below (there were no errors before that).

I am hovering like crazy showing one tooltip after the other but I get no crash. This is on a self-compiled trunk on Gentoo. Any more hints as to how to reproduce the crash?

Hi,

Nepomuk and Strigi have to run and you have to hover a tooltip at the same time Nepomuk / Strigi is indexing this file. Best way to repoduce is to set only one folder to be indexed by Nepomuk while you're hovering in this folder.

When I search for similar error messages, this bug report was the only one that came up.  Dolphin has be crashing multiple times lately.  These are the last few lines from the terminal:

Now, the last few times that dolphin crashed I was using the terminal command "sudo dolphin".  I am running Lubuntu 10.04 (but have KDE 4.5 installed also).  The version of dolphin is: 1.5.  If needed I will supply you with additional information.
Comment 43 Sebastian Trueg 2010-09-02 16:23:23 UTC 
Can this still be reproduced after commit #1170326 which fixes a serious mem corruption bug in libnepomuk related to Types::Entity which is actually mentioned in Frank's valgrind run?

Your problem is unrelated to this bug report. Looks more like bug 251462/bug 252152. If you find out which file causes the crash, please open a new report and attach it.

KFileMetaDataProvider: Don't crash if a Strigi analyzer crashes

Some Strigi analyzers are still unstable and crash under certain circumstances. This patch moves the reading of the meta-data into a custom process instead of doing it in a thread, which assures that a crashing Strigi analyzer does not result in crashing Dolphin or Konqueror when hovering some items.

Comment 46 Sebastian Trueg 2011-02-28 08:47:39 UTC 
@peter: while this is a great solution it would have been really great if you had written this in a manner for it to be reused. We need the exact same for the file indexer (compare the GSOC2011 project idea[1]). Is there any chance you could put the analyzing of a file into a wrapping class that does not use the Nepomuk::Resource API?

Comment 47 Peter Penz 2011-02-28 08:58:43 UTC 
@sebastian: I think it should be no big deal to make this a little bit more generic so that it works also without Nepomuk::Resource API. I coded this part in a few hours yesterday and there are still some things that must be cleaned up; I'll keep your usecase in mind and will let you know when I did an update (but I most probably won't have time for this during the next 2 weeks).
