PIM 16.08 crashes

[Colin J Thomson]

Hi,

The past day or so I have been trying the new PIM release only to find it will 
crash all the time, even sometimes on start-up with no interaction from me.

I think it could be the Webkit + Nouveau crash bug which also stopped me using 
Qupzilla :-(

https://bugs.freedesktop.org/show_bug.cgi?id=91632

https://bugreports.qt.io/browse/QTBUG-41242

Do any of you guys use Nouveau and this latest 16.08 PIM without crashes? 

I see good karma left for for this release on Bodhi which makes me think it is 
webkit/nouveau causing the issue and *not* PIM

Most likely, yes.

It's unfortunate that this has been known for over a year and still no fix. 
I also reassigned several ABRT crash reports to xorg-x11-drv-nouveau (there 
are a few different backtraces, it's not just one bug) in Fedora and didn't 
even get a reply.

Right.

A workaround is to start your kdepim apps with LIBGL_ALWAYS_SOFTWARE=1 or 
QT_XCB_FORCE_SOFTWARE_OPENGL=1 set, e.g.:
LIBGL_ALWAYS_SOFTWARE=1 kmail
or:
export LIBGL_ALWAYS_SOFTWARE=1
kmail

You could even set QT_XCB_FORCE_SOFTWARE_OPENGL=1 globally in some profile 
script, but that's kinda overkill, it would force the llvmpipe for all Qt 5 
stuff including Plasma. (And of course setting LIBGL_ALWAYS_SOFTWARE=1 
globally would be even worse and force it for ALL apps.)

PIM 16.08 [and QupZilla 2] crashes [with Nouveau]

You (and anybody else seeing QtWebEngine (i.e., QupZilla 2, PIM 16.08, etc.) 
crashes with the Nouveau driver) can try these experimental Mesa packages:
https://copr.fedorainfracloud.org/coprs/kkofler/qtwebengine/build/454558/

This applies the experimental patches from:
https://github.com/imirkin/mesa/commits/locking
(except the s/nouveau/noouveau/ hack the author added to allow testing 
multithreading with Warsow). The feedback in the upstream bug report looks 
positive.

I hope this helps,

Thanks for confirming my suspicions,

Yes, since posting and more investigating like you said this has been around 
quite a time sadly,

OK, thanks, I did try this with mixed results and locking up of Kmail at 
times. So sadly I had to use the nV drivers from RPMfusion for the time being 
:-(  Which confirms this was the issue, the plus side is I can use qupzilla 
again.

I will run more tests with nouveau and your suggestions when I get some free 
time again. Sure hope it gets fixed soon so I can return to Nouveau.

Oh that is great Kevin, I'll try these builds as soon as I can.

OK, took me all this time to clear up the nVidia mess, dangling symlinks 
caused all kinds of grief :( And I used RPM not the native installer.
 
I am back running Nouveau finally and testing your mesa packages. So far rock 
solid with PIM 16.08 and I can now also use QupZilla again. No lock-ups or 
crashes at all.

Thanks for providing these packages to test Kevin,

Thank you for your feedback.

I posted this:

I wonder if I will get any reply this time.

Kevin, I've been using your copr packages for a few days now and have had no 
issues with either Kontact or QupZilla, just to let you know.  Thanks!  -A
