Description M. Olson 2015-05-29 18:10:58 UTC

Application: konsole (15.04.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.4-301.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:

Hitting down arrow at the end of shell history, which should result in "bell" sound.  However, sound is muted on this system, so, I don't know if terminal bell sounded.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Paolo Pedroni 2015-06-08 13:46:22 UTC

(In reply to M. Olson from comment #0)
I have the same problem, when I hit <tab> for bash completion and the bell sounds because there's none or more than one completion. The crash is still there in 15.04.2. My backtrace is as follows:

Comment 7 Thomas Lübking 2015-07-16 11:01:36 UTC

No idea whether that'S the cause (legacy config?) but I get a message:
"Invalid URL: QUrl("/home/loki/.local/share/sounds/jaguar/Ping.ogg")" which likely refers to the missing scheme, since the file *does* exist and *is* a proper ogg/vorbis.

However, the notification is not in the hash, so a default object is created (and that's nullptr, but it's usually better to define what you want in return if the key does not exist)

Fixing patch (still no sound, but see error message)

Just updated to the latest konsole (15.04.3) and kf5 packages. The issue still exists.

And since 15.04.3 is not the latest version of konsole can you please specify what "latest kf5 packages" version do you mean exactly?

Comment 23 Alexander Nolting 2015-09-29 11:17:16 UTC

Hello Albert,

it's in my case not fedora I'm working on, but my initial issue was another one (kdiamond) which was closed with a note that the issue is related to the one in this case.

I'm running on opensuse tw and got libkf5 5.14.0-1.1 today.
Alex

Comment 24 Alexander Nolting 2015-09-29 11:43:43 UTC

installed required debug packages and interestingly the crash while closing konsole disappeared. I'm not able to provide any crash log

Comment 25 Thomas Lübking 2015-09-29 12:03:24 UTC

Sure it still happens w/ debug packages uninstalled?
If yes, even a trace with limited symbols is better than none.
If not, your update was simply incomplete ;-)

Comment 26 Alexander Nolting 2015-09-29 12:24:33 UTC

I tested it again after removing debug packages for konsole and libkf5Notifications and libkf5NotifyConfig5 and are unbale to reproduce the issue again. 
I'm fine now.
Thanks!
Alex

Comment 32 Christoph Feck 2016-03-15 23:34:14 UTC

This issue seems to be still present in latest KF5 release 5.19.0, see bug 360449.

Comment 33 Thomas Lübking 2016-03-15 23:53:28 UTC

Seems as if notificatiion objects in the hash are deleted elsewhere (flags only returns a member and the KNotification::this pointer isn't null, so it's garbage)

connect(notification, &KNotification::destroyed, this, [&](QObject *o) {m_notifications.removeAll(o);});

in NotifyByAudio::notify should likely catch that.


Please notice that I'm not available for providing patches anymore.

If you still get this crash with this version, please add a comment, or file a new ticket with an updated backtrace.

Sadly no, i messed up that system (i tinker too much). But the crash happen when i was changing font options in system settings, enabling anti-aliasing to be exact.

I posted the bug here fallowing the suggestions of the bug reporting tool.

Comment 51 Albert Astals Cid 2016-10-03 20:26:46 UTC

Rene can you reproduce it all the time? If so can you run it thorugh valgrind?

Comment 52 RJVB 2016-10-03 20:50:30 UTC

Sadly, no. I cannot recall having seen this crash, but I also do not normally get an audio notification when I do a git commit through KDevelop. If ever it becomes a habit I can try to provoke this while running through valgrind (but that in itself is a bit more than my machine can handle, for KDevelop at least).

I noticed this in my backtrace:
    #16 0x00007fc783a11aa8 in QCoreApplication::sendPostedEvents (receiver=receiver@entry=0x0, event_type=event_type@entry=0) at /opt/local/var/lnxports/build/_opt_local_site-ports_aqua_qt5-kde-devel/qt5-kde-devel/work/qt-everywhere-opensource-src-5.6.1/qtbase/src/corelib/kernel/qcoreapplication.cpp:1513

is it possible that this crash is the result using delete instead of ->deleteLater() on an object pointer inheriting QObject and representing a widget (or otherwise be a potential recipient of GUI events)? That would explain why the crash isn't systematic.

Created attachment 101792 [details]
latest backtrace from KDevelop5

I'm still getting this crash with frameworks 5.27.0 and KDevelop5, but very sporadically.
Running Qt 5.6.1, kernel 4.5.7 with Con Kolivas patches.
I'm attaching the backtrace, hoping that will get me around BKO's spam filter (GRRR!)

Comment 61 Kevin Funk 2016-10-26 10:22:44 UTC

@René: Fixed by https://git.reviewboard.kde.org/r/129092/. Part of KF5 5.28.

Comment 62 RJVB 2016-10-26 10:39:38 UTC

OK, thanks, will test. Sadly I don't know how to trigger the crash so we'll just have to cross fingers this time it's really fixed.

Comment 63 Albert Astals Cid 2016-10-26 20:38:05 UTC

(In reply to Kevin Funk from comment #61)
> @René: Fixed by https://git.reviewboard.kde.org/r/129092/. Part of KF5 5.28.

I'm actually not convinced that patch fixes this crash, it fixes *a* crash in NotifyByAudio, but the backtrace I could reproduce was different, so I'm not convinced it fixes this one.

Comment 64 RJVB 2016-10-26 21:21:18 UTC

We'll see. I've applied the patch to my 5.27.0 systems and will update this ticket when I get another crash.

As noted in the backtrace I am still on KF 5.26.  I will upgrade to 5.28 and see if this persists.  Oddly I have been on 5.26 since 22 September with no crash until now.  uptime(1) shows only 10 days 2 hours 41 minutes, so it doesn't look related to that either.  Just random.

Comment 68 RJVB 2016-11-28 08:25:32 UTC

The KNotification file(s) in the backtrace may not even have evolved since 5.26 but indeed it's highly likely that the cause is elsewhere (= not in the functions on the trace) given how difficult it is to reproduce the error.

Do we know what alert this happens with, and how it's configured?

Comment 69 RJVB 2016-12-01 08:48:59 UTC

As if it's contagious: I had another one of these crashes in KDevelop, with 5.27.0 installed.

And then just now dolphin5 crashed on me when I tried to suppress a file (with Shift-Del to delete it without going through the wastebin).

This puts up a notification ("are you sure") and plays the same alert sound as KDevelop will play, I think because the "Warning Message" from the Plasma Workspace notifications is triggered. On my end that plays Oxygen-Sys-Warning.ogg .

I didn't get a usable backtrace from Dolphin, but when I reopened the folder in question I noticed that
- the file was still there (=> the crash happened during the notification)
- when I repeated the same action, it was then that I realised a sound was being played, because this time I didn't hit the Enter key as soon as I saw the dialog appear.

So I think we may be looking at something akin to GUI widgets being deleted while events are still pending (or can still be generated for them) because of `delete widget;` instead using `widget->deleteLater();`. It's weird that this would be required for alerts with an asynchronous nature (which sound alerts have by definition if they play through a sound daemon?), but I presume this could be a side-effect of providing an application's widget as the parent for a QObject inherited by a (hypothetical) KNotifications instance.

I hope I'm not rambling too much here, but this would explain the random nature of the crash: it depends on system load and to what extent the sound alert can be processed sufficiently to be able to cope with its infrastructure being taken down under its feet. With the dolphin crash I just had something like this was clearly going on: the laptop had just been woken from sleep, no sounds had been played yet, it was updating the locate and/or apt databases (etc), so pulseaudio must have taken just long enough to be swapped in to allow me to accept the warning message before the alert sound had even started to play.

Another potentially relevant observation: I use the VLC phonon backend (latest version, git master/head).

The system that I experienced my most recent crash on is used as a buildbox and was building Firefox when the crash happened.  System load was high and my wait time was low; I hit Alt+F4 and immediately Alt+D to 'D'iscard the unsaved changes in KWrite.  I'm not sure the dialogue even popped.

I'm not running -HEAD, but I am running Phonon-VLC as well - version 0.9.0 here.

Comment 73 RJVB 2017-02-14 13:41:37 UTC

This is probably not related but then again maybe it is:

smb4k (git/head) has been crashing on me when quitting, with the backtrace below. In this case it looks like there is a bug in VLC 2.2.4 where certain libvorbis resources are freed twice, or attempts are made to free resources that were never allocated. Rather easy to prevent in VLC's function `Ogg_CleanSpecificData()`.

I mention this here since double frees or null pointer dereference doesn't always lead to an immediate crash, but can lead to seemingly random events later on. Can we be certain that this longstanding ticket/bug has nothing to do with this Ogg issue? After all KDE uses .ogg files for audio notifications...

Created attachment 109891 [details]
New crash information added by DrKonqi

kdevelop (5.2.1-28-g94ed49acea) using Qt 5.9.3

- What I was doing when the application crashed:

Here's a fresh backtrace with Qt 5.9.3 .

I notice that KNotificationManager::self() is called from what seems to be an exit handler registered through atexit(). That's generally not a splendid idea; I just traced a known crash-on-exit crash to deleting a Qt object via atexit(), which apparently interferes with Qt's way of handling the global destruction phase. Question is, if atexit() is indeed involved, who's responsible for that?

Would it be an idea to address this long-standing issue by connecting to the QCoreApplication::destroyed signal, releasing KNotification resources upon receipt of that signal and (or at least) preventing the framework from being used from that moment?

Comment 88 A. Wilcox (awilfox) 2018-09-28 03:21:04 UTC

Comment 69, Comment 70, Comment 86 provide enough information to mark the NEEDSINFO flag invalid, imo.  -> Reported

Comment 89 Albert Astals Cid 2018-09-28 20:33:07 UTC

No, it doesn't, the at-exit crash fix for is only in KF 5.47 so he's using an old version.

at-exit crash is bug 380114

And Rene should remember since he was part of the review in phabricator.
