Hello and thank you for this bug report!

I'm not sure that it's due to the dock but is it possible to have more details about this bug? Is it possible to reproduce it every time?
According to the Stacktrace, it seems that you had this bug after having opened/closed a menu, is it correct? Then the dock will crash when freeing memory because GTK/GLib tries to allocate 103.079.215.112 bytes (~100Go of RAM), it's a bit too much :-)

@fabounet: any idea? :-)

Hi !
A this stage it's really random by me.
I'm on Trusty, so I did'nt mind much ;)
I sometimes launch several programs, then waiting for them to open.
If I get more clues on specifics, i'll leave them here.

The only odd stuf I noticed is that, usually it restarts easilly by relaunching cairo, but I had an instance where, i had a "ghost" instance of cairo behind the operating relaunch untill reboot.

to give you clues on my memory management, I set my /etc/sysctl.conf to :
vm.swappiness=5
vm.vfs_cache_pressure=50
