gnome-settings-daemon crashed with SIGSEGV in gnome_bg_draw()

[Stefan Kriwanek (Divan)]

Binary package hint: gnome-settings-daemon

For a few days now the Gnome desktop shows up in some default style after booting and I find the following in dmesg:

[ 47.974605] gnome-settings-[1789]: segfault at 7fcb18b12000 ip 00007fcb21b1f0c4 sp 00007fffd05aa050 error 7 in libgnome-desktop-2.so.17.0.1[7fcb21b09000+28000]

This happens again after every logon:
[ 503.640707] gnome-settings-[2356]: segfault at 7f3753630000 ip 00007f375c63d0c4 sp 00007fff53042d40 error 7 in libgnome-desktop-2.so.17.0.1[7f375c627000+28000]

However, running gnome-appearance-properties (which runs gnome-settings-deamon again) restores the humanity style and doesn't produce any errors in dmesg. Starting gnome-settings-deamon by hand shows:

Crash in gnome-desktop

[Matthias (matthias-redhat-bugs)]

I think we probably need to ensure that rect is entirely contained in the pixbuf extents, in pixbuf_draw_gradient

I've noticed that since the crash gnome-settings-daemon does not
start (crashes each time) when I log in (e.g. fonts in gnome-panel
& nautils are weirdly huge). Relatively quick workaround is to
open the "Change desktop background" dialog (settings daemon is
launched) and restart nautilus.

Before the first crash it was all OK. Any idea which settings
cause these crashes? Can I do some quick cleanup which could help
me to get rid of this?

[Matthias (matthias-redhat-bugs)]

run it under gdb and see where it crashes ?

[Petr (petr-redhat-bugs)]

I've already submitted the backtrace to my original bug:

    https://bugzilla.redhat.com/attachment.cgi?id=381534&action=edit

It fails in the pixbuf_draw_gradient you mention in comment #3.
Sorry, I don't know any details about what this function does, so
I'm not able to figure our what setting could cause these crashes.

The issue is gone since yesterday (02/17) - gnome-settings-daemon now runs correctly on boot.

However, it still reports the failed assertion.

[Stefan Kriwanek (Divan) (dev-stefankriwanek)]

Sorry, I have to correct myself:

There's no assertion anymore.

Instead, gnome-settings-daemon does load correctly on boot if and only if there's no monitor connected to the VGA port on boot (notebook).
