this is a theme related startup crash affecting linux users after the update to firefox 46. in early 46.0 crash data these signatures crash makes up the absolute majority of crashes on linux.

Comment 1

[Liz Henry (:lizzard) (relman/hg->git project)]

Karl, any ideas? I'm pinging you since the stack says gtk3. Is this a particular theme?

Comment 2

[Xavas]

I have the same issue on the KDE distro, this only affects oxygen-gtk theme.

Comment 3

[Marco Castelluccio [:marco]]

This is a startup crash and in the top 10 of the Firefox 46 top crashers, so pretty serious.

FYI, https://en.wikipedia.org/wiki/Oxygen_Project
"The Oxygen theme set is used by default for Plasma Workspaces in most Linux distributions, like Fedora,[2] Kubuntu,[3] and openSUSE."

Comment 5

[Karl Tomlinson (:karlt)]

This is https://bugs.kde.org/show_bug.cgi?id=331020
which was fixed in 
https://quickgit.kde.org/?p=oxygen-gtk.git&a=shortlog&h=vgtk3-1.3.4

Ubuntu have back-ported the fix [1], and so crash rates should be dropping.
Fedora took the fix long ago. [2]

The oxygen-gtk engine was assuming that the cairo_context_t passed to
gtk_render_frame() is the same as previously passed with a "draw" signal
emission on the widget.  The rendering API was designed to not even need a
widget [3] and so Gecko does not emit a "draw" signal on a widget.

The engine registers an "OxygenVersionContainer" type with
"VersionString" qdata, so it would possible to detect old versions and switch to a fallback theme, but we wouldn't know whether old versions have a back-ported fix.

Comment 7

[Liz Henry (:lizzard) (relman/hg->git project)]

I don't see this in the top crashes for 46.0.1 any more. 
Is there still something more to do from our side (a bit late to be asking this for beta, but, say, for 48)  or would you call this fixed?

Comment 8

[Karl Tomlinson (:karlt)]

We could call this WORKSFORME.

I would probably take a patch to fallback to the default GTK theme, even though that would affect users with fixed oxygen-gtk, but writing the patch is not a priority.

Comment 9

[Marco Castelluccio [:marco]]

The crash still exists, so I wouldn't call it WORKSFORME (but WONTFIX if we don't plan to fix it).

It isn't a top crasher anymore on Firefox 46 (expected, since the Linux population is extremely small on Release compared to the Windows one), but it isn't a top crasher in Firefox 47 either.

This means that either the affected users managed to update oxygen-gtk, or that they stopped using Firefox (since it crashed on startup and so they couldn't use it anymore).

Comment 10

[Karl Tomlinson (:karlt)]

Thanks.  Leaving the bug open is fine.  WONTFIX is only if we would not take a patch.  The Linux port depends on contributors offering to fix bugs, and so we don't close bugs just because no Mozilla employees are fixing them.

To clarify, fallback would only occur in old versions of oxygen-gtk (even though some of those old versions may be patched by the distribution).

This situation is a little complex because different versions of GTK require different theming engines and so there are several branches of oxygen-gtk.  I don't know exactly how many were affected, or at which stage.

Comment 12

[Milan Sreckovic [:milan] (needinfo for best results)]

Should we do more evangelism on this one?

Comment 13

[Karl Tomlinson (:karlt)]

Problems with oxygen-gtk include this and bug 1268395.
They are each fixed by changes to oxygen-gtk.

Reporting bugs to the distributions that are still shipping affected versions seems appropriate.  It would be helpful if people experiencing the problems could do that.

Comment 14

[Lawrence Mandel [:lmandel] (use needinfo)]

Updating status flags.

Comment 15

[Liz Henry (:lizzard) (relman/hg->git project)]

Can we call this fixed? Marking fix-optional for now.  There are a few scattered crashes remaining and I don't think anyone is planning on submitting a patch to fix anything on our side of things.

Comment 16

[Karl Tomlinson (:karlt)]

Resolution WFM meaning fixed in oxygen-gtk.

Comment 17

[diego.ml]

I've reported this for RHEL 7:
https://bugzilla.redhat.com/show_bug.cgi?id=1376205

Comment 18

[diego.ml]

This is fixed even in RHEL / Centos 7 now.
