plasma: Fix applet actions might be nullptr

Comment 2 David Edmundson 2015-10-07 15:22:48 UTC

That patch won't fix it.

#6 0x00007f94710d3810 in Plasma::Applet::actions() const (this=0x0) at ../../../src/plasma/applet.cpp:571

it's the applet that's null.
It's the use of  d on a null pointer that's causing the crash.

I'm still seeing this on Debian sid. 4:5.4.3 happens when I unsleep the laptop, especially when the monitor configuration has changed. (e.g. plugging in a different external monitor and resuming).

I'm using a thinkpad x220 tablet, looks like I have an intel card using mesa 11.0.6. (Below is the lspci output for the VGA card).

Plasma crash after laptop wake up (un sleep) when having an external display attached

Comment 19 Nadav Kavalerchik 2015-12-12 09:26:58 UTC

I have attached the above a crash report, as I am experiencing the same issue with my ThinkPad T440s + Kubuntu 15.10 + KDE 5.15 + QT 5.4.2

Comment 20 Xuân Baldauf 2015-12-26 21:17:26 UTC

I'm experiencing the same issue.

The bug is that in this code https://quickgit.kde.org/?p=plasma-workspace.git&a=blob&h=17ce61b57f71332b9b4029d44301462ef90d3dfd&hb=1f826604749f36e899034d55d02a910e31584f60&f=shell%2Fshellcorona.cpp

>    DesktopView *view = new DesktopView(this, newScreen);
>
>    Plasma::Containment *containment = 	(m_activityController->currentActivity(), m_views.count());
>    Q_ASSERT(containment);
>
>    QAction *removeAction = containment->actions()->action(QStringLiteral("remove"));

"m_views" is empty, and thus "m_views.count()" is zero. Hence "containment" is NULL, so dereferencing this pointer triggers the crash.

Comment 21 Paulo Fidalgo 2016-01-06 09:40:01 UTC

Happened with me again, after removing the .kde .config and .shared directories to have a clean start.

Comment 23 David Edmundson 2016-02-01 22:49:19 UTC

> "m_views" is empty, and thus "m_views.count()" is zero

Well that's right.
That's saying. Get me the contianment for screen 0.

The bigger question is why createContainmentForActivity() returns a null pointer.

Comment 24 David Edmundson 2016-02-01 22:55:24 UTC

Possible causes:
m_desktopContainments[activity][0] is a valid entry, but null.

containmentForScreen(int, QString, QVariantList) returns a null pointer.

which would happen if defaultPluginIfNonExistent doesn't exist
OR 
we fail this check
        if (screen >= 0 && screen < numScreens()) {

Comment 25 David Edmundson 2016-02-01 22:56:13 UTC

Edit.
Urgh. It's obviously the latter because that uses the qscreen API rather than the KScreen API triggering this.

Will fix.

Git commit 5a1a411b41f950e97d80ff7c898052fb6d02fb1a by David Edmundson.
Committed on 03/02/2016 at 17:32.
Pushed by davidedmundson into branch 'master'.

Fix the Plasma::Applet::Actions crash

We were mixing KScreen and QScreen API.

Corona.cpp checks we are requesting a containment for a valid screen
if (screen >= 0 && screen < numScreens()) {

This fails as numScreens() is Qt API based, whereas the signal we're
adding the output for is ShellCorona::addOutput

Comment 28 David Edmundson 2016-02-03 17:36:02 UTC

I've only pushed this in master as I fear there may be some fallout.

If people can test and let me know I might backport it.

Comment 29 Stefan Radermacher 2016-02-03 17:58:00 UTC

This patch does not seem to fix the problem I reported in bug 358919.

Comment 30 David Edmundson 2016-02-03 22:07:12 UTC

@Stefan 

Oh. Can you ensure you have the patch, and can I have a new BT please.

Comment 31 Stefan Radermacher 2016-02-03 22:36:31 UTC

Sure. To make sure I removed the Qt patch I mentioned in my earlier bugreport and to make sure I have your patch, I recompiled the  kde-plasma/plasma-workspace-5.5.4 package again. Here's the start from the compile log, where it lists the patches used (plasma-workspace-5.5.4-crash-fix.patch is your patch):

>>> Emerging (1 of 1) kde-plasma/plasma-workspace-5.5.4::gentoo

So I think this is covered. I have a new backtrace generated by simply turning off my main monitor and then turning it back on again, but it is too big to paste here, so you can find it here: https://paste.kde.org/pcdzif4s7

Comment 33 Stefan Radermacher 2016-02-03 22:55:55 UTC

Interesting. Maybe then my original bug report should not be classified as a duplicate?

Comment 34 David Edmundson 2016-02-03 22:57:45 UTC

Your original report was a duplicate, the trace you just uploaded is different to your original one.

(it's a dupe of the QScreen animation timer one... which is somewhere else, fixed in newer Qt)

Comment 35 Stefan Radermacher 2016-02-03 23:00:06 UTC

So, should I try again with the Qt patches I had installed when I made the original report?

Comment 45 Stefan Radermacher 2016-05-14 09:26:34 UTC

I'm still getting plasmashell crashes everytime my monitors wake up from standby. KF 5.21, Plasma 5.6.4, Qt 5.6.0. Plasmashell is usually gone when they wake up, and my windows have been moved around. I do not get a Dr. Konqui message box anymore, though, the shell is just simply gone, so I can't post a trace.

Comment 46 Stefan Radermacher 2016-05-14 09:29:13 UTC

Addendum: this is what I get after the crash in the terminal when I start plasmashell from there:

Same here :-(

Comment 48 Stefan Radermacher 2016-06-03 10:04:50 UTC

It seems the upcoming Qt release fixes the plasmashell crash.

I'm not sure why this marked as resolved fixed, since in Fedora 23, running plasma 5.6.5, it's still very reproducible.   I verified that the SRPM for Fedora 23's latest updates contain the fix in the commit listed at the top of this ticket, and my previous bug (marked duplicate, 364613) contains as much debug information as I could retrieve to state that.

Since  I can very reliably reproduce this bug, what can I do to help fix it?

Sorry for reviving this old issue.
I can reproduce this issue every time, even with the newest Kubuntu 20.04 LTS (In 18 and 19 too). I can't find any threads of bug reports that end with a proper solution for this issue. I am not an Ubuntu expert, but the errors as seen below and the issues described in bug seems very similar, so I assume it is related?
