pantheon-wallpaper segfaults

[Arturo Torres Sánchez]

I'm using version 0.2-0~24~oneiric1, and launching it from the terminal gives me the following output:

[L_INFO 13:41:25.029522] [Application:79] Pantheon Wallpaper version: 0.2.0
[L_INFO 13:41:25.029641] [Application:82] Kernel version:
Violación de segmento (nekropsio elŝutita)

Well, my system is in Esperanto and Spanish, but the last line translates as
Segmentation fault (core dumped)

Simply reporting a segfault doesn't help developers fix the problem. Please post a full backtrace of the segfault and attach it to this bug report, and state any relevant software/hardware information such as OS, version, graphics card, graphics driver, etc.

Sorry, I'm just a noob.

Do you mean this:

Is that enough?

Same problem here.

Im using Oneiric beta 1, also using ATI video card (integrated Radeon HD3200), maybe it's the problem? I have no support from amd for now...

[David Gomes (davidgomes)]

I am using Intel Graphics Card, Ubuntu Oneiric 1, turned to ElementaryOS Luna. I am getting the same error:

Program received signal SIGSEGV, Segmentation fault.

Not sure if it helps but I'm additionally getting this:

(process:3705): GLib-GObject-WARNING **: specified instance size for type `WallpaperWallpaper' is smaller than the parent type's `GraniteApplication' instance size

[Erasmo Marín (erasmo-marin)]

getting this also right now:

h4k@destructor:~$ pantheon-wallpaper

(process:841): GLib-GObject-WARNING **: specified instance size for type `WallpaperWallpaper' is smaller than the parent type's `GraniteApplication' instance size

(process:841): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed

(process:841): GLib-GObject-CRITICAL **: g_object_new: assertion `G_TYPE_IS_OBJECT (object_type)' failed
Violación de segmento (`core' generado)

first warning looks like a Vala memory problem or what...

[Sergey "Shnatsel" Davidoff (shnatsel)]

These segfaults were probably caused by Granite ABI mismatch and uninitialized dconf values. I can't reproduce this issue anymore.
