Comment 1 Frank Reininghaus 2013-05-22 06:19:55 UTC 
Thanks for the bug report. You could help us to possibly find the cause of the crash by running Dolphin in Valgrind:

1. valgrind dolphin 2> log.txt 
(note that Dolphin will run very slowly).

2. Reproduce the crash.

3. Attach 'log.txt' here.

Thanks for your help.

log.txt

Thanks for your reply. So, when I run Dolphin with valgrind, the
Dolphin didn't crash, but when I run Dolphin without valgrind, I can
always reproduce the crash. I try it 3-4 times. I attach the log.txt
file here.

Comment 3 Frank Reininghaus 2013-05-23 09:04:19 UTC 
Thanks. The Valgrind log shows only invalid reads, not writes, so I don't know if the reported errors (none of which come from Dolphin itself) have anything to do with the problem.

It might have something to do with the stuff that is going on in the other threads - their backtraces are incomplete and look strange. In particular, it's very strange that there are frames from libQtDeclarative.so.4 in there. I'm not aware of anything in Dolphin that makes use of QtDeclarative.

Unfortunately, I don't have any idea what else could be done to find out more about the problem. However, it seems unlikely that the crash is Dolphin's fault.

dolphin (4.11.2) on KDE Platform 4.11.2 using Qt 4.8.4

- What I was doing when the application crashed:
Just plugged in an external HDD. After that Dolphin crashed.

Comment 9 Frank Reininghaus 2013-11-14 10:23:35 UTC 
I don't think that this is a Dolphin issue. I see nothing related to Dolphin in the backtrace. Moreover, the crashes only started with KDE SC 4.10, and there were, to my knowledge, no Places-related changes between 4.9 and 4.10 in Dophin.

However, I do see a change in kdelibs prior to 4.10 which changes the way KBookmarkManager deals with toolbars:

https://projects.kde.org/projects/kde/kdelibs/repository/revisions/92d2484a4b0ba692a78faa83ceca851a6511f4f5

It appears that this commit might be related to the cause of these crashes. I'll CC Stefan Brüns, who committed that change.
Comment 10 Stefan Brüns 2013-11-14 17:36:48 UTC 
I see one possible problem here, QDomNode::toElement returns a NULL element if it is e.g. a AttributeNode or TextNode, so e.tagName(...) might crash.

Patch is available at
https://git.reviewboard.kde.org/r/113866/

Reporters:
Can you attach your bookmarks file, so I can verify if this is possibly the cause of the crash?
The file is located under:
~/.kde4/share/apps/kfileplaces/bookmarks.xml

If you have privacy concerns, this will remove the critical information:
sed -e '{s/href="\([^:]*\):.*"/href="\1:XXX"/g}' ~/.kde4/share/apps/kfileplaces/bookmarks.xml > bookmarks_cleaned.xml

Comment 12 Stefan Brüns 2013-12-16 16:40:05 UTC 
I tried to create a testcase, but even inserting bogus content (e.g a textnode) in the bookmarks file has not triggered the crash, so most likely a failing toElement() is out.

But unfortunately none of the reporters has provided a bookmarks file, so this can not be ruled out completely.

As the crash seems to happen randomly, can we rule out any threading issues?

Committed on 11/01/2014 at 16:32.
Pushed by aacid into branch 'KDE/4.12'.

kio bookmarks: Only iterate over element nodes in findToolbar()

Only iterate over element nodes, and filter on <folder> tag.

findFirstChild/nextSibling might return a node which is not an QDomElement. toElement will return NULL and accessing it will crash.

Possible fix for 320006

We are still seeing this crash with 4.12.2 (which ought to contain the latest commit) on the automatic Ubuntu error tracker.

This time it crashes in:
QDomNode::isElement() const () from /usr/lib/x86_64-linux-gnu/libQtXml.so.4
QDomNode::firstChildElement(QString const&) const () from /usr/lib/x86_64-linux-gnu/libQtXml.so.4

my apologies - it has just been explained to me that:
open source is a meritocracy

And now I Understand why michael young warned against the rise of the
meritocracy
http://books.google.co.uk/books/about/The_rise_of_the_meritocracy.html?id=e_rTyIMJR9kC

because its no different from any other form of:
small secret society corruption
of who are you?
of what have you contributed?
of why should I treat you with any respect?

So I guess i shouldn't be surprised that open sources is not new - its
just the same old pigs in the masters clothing

Please do not mail privately.

When comparing the backtraces of this bug (the 4.11 version of it), and bug 336762, you will see that they are identical, even if the steps are different. As such, we mark those bugs as duplicates.

In case there is something I missed, please add a comment here.

New crash information added by DrKonqi

dolphin (4.14.2) on KDE Platform 4.14.2 using Qt 4.8.6

- What I was doing when the application crashed:

Mounted USB flash and chosen to open with Dolphin.
It happens quite often with other USB storages.

Would this patch help?
http://www.davidfaure.fr/2015/kbookmarkgroup.diff

Otherwise I would need a valgrind log.

Comment 44 Stefan Brüns 2018-04-21 18:28:24 UTC 
I am about to close this one as WORKSFORME.

There have been several requests for the bugreporters to provide feedback, but none have.

Bug reports are not one-way, and bug reports are not a popularity vote. If you can not be bothered to report back, refrain from filing one in the first place, you are just adding useless noise.
Comment 45 Rick Alther 2018-04-21 18:55:13 UTC 
Been 4 years since I reported my crash in Dolphin, but I'm not able to reproduce it now.  Plug USB drive in/out, Dolphin already open/not open, sitting in USB directory when unpluggged.  Dolphin handled all those scenarios.
I'm currently running:
Dolphin 17.0.4.1
KDE Frameworks: 5.44.0
Qt: 5.9.4
Kernel: 4.15.17

Legacy KDE 4.x or Qt 4.x (or even old kernel) bug?
Comment 46 Stefan Brüns 2018-04-21 19:08:23 UTC 
@ Rick Alther:

Thanks for the feedback! Note, in 2014 you still might have been affected by a bug, where the code called .toElement() on a non-element. This has been fixed in 2014.
Comment 47 Nate Graham 2018-04-21 19:09:13 UTC 
Thanks for checking, Rick! Let's say it's been fixed. If we get any new reports, we can re-evaluate.

Just to say that it's not fair to complain about missing feedback in 2018 when the back was originally reported in 2013 (5 years ago!) and most reports are dated 2013-2014-2015, often created with the automated error reporting system DrKonqi. People may have changed system, Linux version, Linux distribution, KDE version and so on. Additionally, consider this bug was not systematic, at least for me. I personally experienced it a couple of times and DrKonqi led me here.

This said, I can say it has been a long time since I've last encountered this problem and I agree it can be considered fixed for now.

First of all i reported the problem not to long ago from kdecrash application and i thought it will include the logs since it had some options for it (at least thats what i thought it was saying) this was the first time i used the program.
When i saw it getting marked as a duplicate and the first report being 2013 i uninstalled the kde from my arch.

Since i dont have the logs now i can tell you what i was doing:

I was connecting to a Synology Diskstation (mount with cifs) thats where the problems was starting and there where many of them.

on idle with split view on thats when this bug happen
But there was other crashes from time to time when i was exploring on diskstatio and opening the folders with big images (around 100-500mb each mostly corel and psd).
it would never happen if i was on my own 2 disks (but i didnt had a lot of images on my disks).

I switched to i3 and i am using thunar again with 0 problems

I asked for feedback in 2014, and I asked again in 2018.

You are apparently able to give feedback now. Why haven't you provided information any earlier, either details how to reproduce, or stating you can no longer reproduce the bug?

So, by "several requests" for feedback you mean twice, the second time 4 years after the first one?

I can't see your feedback request in 2014. I see you worked on this bug in 2013 and, if I understand it correctly, this bug should have been fixed in KDE 4.12.
My first report here (that is, when I learnt about this problem) is AFTER your fix and I experienced this in KDE 4.13, which, I would say, should not have the problem.

Now, your latest request (and the only one since I've been here) is dated 2018-04-17, that is less than a week ago, in a bug report that is more than 5 years old. I don't think it's so much time...
I didn't give feedback before yesterday because:
1) I didn't have time to write here before yesterday
2) saying that I can't reproduce NOW (and within your less-than-a-week time frame you have given us) a problem which is intermittent, is not very informative... unless, of course, you're seeking a (not so strong) reason to close this without any further investigation
