cairo-dock crash if applications menu enabled, segfault

[luke]

Using cairo-doc version 3.4.0 in Ubuntu Vivid Vervet (alpha version of Ubuntu), installed from Ubuntu packages.

cairo-dock_3.4.0-0ubuntu1_all.deb
cairo-dock-core_3.4.0-0ubuntu1_amd64.deb

To reproduce, install cairo-dock from these packages and their dependencies into Ubuntu Vivid as last updated on or after Nov 21. Enable the applications menu and attempt to start the dock. No difference between opengl and cairo rendering, the crash always occurs either way.

Cairo-dock core has not updated since 3.4.0 came out in Utopic, plugins have updated once. Rolling back the plugins versions has no effect.

Crash started (every time) beginning with the Nov 21 round of updates to Ubuntu vivid, and not present after the Nov 16 round of updates (no updates between those dates, not enough bandwidth at home), cairo-dock can no longer start normally if the applications menu is enabled, opening into maintainance mode instead with a crash and restart listed if started in terminal.

Experimenting with launching from from terminal and attempting to enable the menu by various means I got these results, a debug.txt file is also attached to this bug report:

As desklet, enabling from inside module configuration (does NOT write to config file!):

g_strsplit: assertion 'string != NULL' failed
g_once_init_leave: assertion 'result != 0' failed
warning : (/build/buildd/cairo-dock-3.4.0/src/cairo-dock.c:_cairo_dock_intercept_signal:180)
  Cairo-Dock has crashed (sig 11).

As desklet, enabling from main configuration

context mis-match in pipe_sampler_view_release()
g_strsplit: assertion 'string != NULL' failed
g_once_init_leave: assertion 'result != 0' failed
warning : (/build/buildd/cairo-dock-3.4.0/src/cairo-dock.c:_cairo_dock_intercept_signal:180)
  Cairo-Dock has crashed (sig 11).
It will be restarted now.
Feel free to report this bug on glx-dock.org to help improving the dock!
info on the system :
Linux ubuntu 3.18.0-999-generic #201411162130 SMP Mon Nov 17 02:31:34 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Couldn't guess if it was an applet's fault or not. It may have crashed inside the core or inside a thread
restarting with 'cairo-dock --keep-above -m -q 3'...

MORE DETAILS:

context mis-match in pipe_sampler_view_release()
Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture2D
g_ptr_array_free: assertion 'rarray' failed

Comes up in the terminal BEFORE crash, while running configuration screen in "-T" mode, these 4 lines come up in the crash when enabling applications-menu:

g_ptr_array_free: assertion 'rarray' failed
g_strsplit: assertion 'string != NULL' failed
g_once_init_leave: assertion 'result != 0' failed
Segmentation fault

Incompatable package identified:

Updating from Trusty's version of libgnome-menu to

libgnome-menu-3-0_3.10.1-0ubuntu4_amd64.deb

breaks the applications menu in Cairo-dock, but you may have to reboot after the update to reproduce the crash to maintainance mode (normal start) or segfault indication (test mode). Reverting the package to the prior version fixes the menu,

Hello and sorry for the huge delay,

Do you still have this crash? It should have been fixed after having recompiled the the plugins due to the upgrade of libgnomemenu.

I am now on Debian Unstable, just reinstalled cairo-dock to test, menus work fine.
