Description Joachim Mairböck 2014-03-23 18:16:48 UTC
Application: konqueror (4.12.95)
KDE Platform Version: 4.12.95
Qt Version: 4.8.5
Operating System: Linux 3.11.10-7-desktop i686
Distribution: "openSUSE 13.1 (Bottle) (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
Konqueror hanged, therefore I killed and restarted it (via docked taskbar icon). It restored the session, but also showed my home folder (different bug?). Soon after restarting, it crashed. It still had not recored the home folder tab in Session Restore, because this one was not restored after the crash, so the crash happened rather early.

-- Backtrace:
Application: Konqueror (konqueror), signal: Aborted
Using host libthread_db library "/lib/libthread_db.so.1".

Reported using DrKonqi
Comment 1 Frank Reininghaus 2014-03-23 19:02:34 UTC
Thanks for the bug report.

@Emmanuel: it seems that Thomas Richard is still the default assignee for "plugins: dropbox". Shall I change that and make you the default assignee for this product? (dolphin-bugs-null is currently always added as CC automatically for new reports, and I think we should keep that).
Comment 2 Emmanuel Pescosta 2014-03-23 23:14:24 UTC
> Shall I change that and make you the default assignee for this product?
If you prefer it, yes.

Yes definitely, just started watching this list ;)
Comment 3 Emmanuel Pescosta 2014-03-24 00:19:26 UTC
I'm afraid that we can't do anything about it in Dolphin.

I think it is a bug in Qt, looks like fd_set, select, ... related problems.
According to __chk_fail () there is a bufferoverflow somewhere?!

http://refspecs.linux-foundation.org/LSB_4.0.0/LSB-Core-generic/LSB-Core-generic/libc---chk-fail-1.html

Can you reproduce this crash?

Thanks for your help!
Comment 4 Joachim Mairböck 2014-03-24 07:39:57 UTC
I had the same situation occur again yesterday, and it crashed again like this (I didn't inspect the stack trace though). I also haven't tested it in Dolphin alone, or at least it never occured to me there yet.
Comment 5 Emmanuel Pescosta 2014-03-24 15:29:30 UTC
Can you provide some more information?
Any special settings?
Does this problem occur randomly or after some specific time?
High or normal memory usage in Konqueror?
Big folders?
Dropbox client version?
...

Thanks for your help!
Comment 6 Joachim Mairböck 2014-03-24 17:42:52 UTC
I just tried opening my home folder (which contains my Dropbox folder) in standalone Dolphin. It crashed too, nearly instantly (after 2 seconds). So this is independent of Konqueror. DrKonqi didn't appear though.

I have about 1.7 GB in my Dropbox folder, some of them are shared with others.

Dropbox Version 2.6.5

I'll attach a log of the console output of Dolphin.

Console output from crash
Comment 8 Frank Reininghaus 2014-03-24 22:54:29 UTC
@Joachim: Running Dolphin in Valgrind might help to identify the cause of the problem, but I'm not sure. In any case, it will make Dolphin quite slow, so I don't know if testing this will work reasonably. If you want to try it, have a look at

http://community.kde.org/Dolphin/FAQ/Crashes

Thanks for your help.

> > Shall I change that and make you the default assignee for this product?
> If you prefer it, yes.

OK, I'll change that then. Thomas is not actively working on the plugin any more AFAIK, so IMHO it does not make much sense to have him as the default assignee.

OK, that's good :-)

Valgrind log

I have tried running Dolphin under valgrind and attaching the log here.

Interestingly, DrKonqi appeared, which otherwise didn't happen when running Dolphin standalone.
Comment 10 Frank Reininghaus 2014-03-30 16:24:38 UTC
Thanks for the Valgrind log!

The interesting part seems to be this error output from the application:

QObject: Cannot create children for a parent that is in a different thread.
(Parent is QTcpSocket(0xcebfbac), parent's thread is QThread(0xad4fb88), current thread is UpdateItemStatesThread(0x110eafa0)
KCrash: Application 'dolphin' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
dolphin: Fatal IO error: client killed

Apparently something in the UpdateItemStatesThread tries to create a child for a parent QObject that belongs to the main thread?

Great :) Thanks for testing!
