Hello Guy and thank you for this bug report,

What did you do exactly before the crash? Clicking on an icon? Opening a new application?
(if you really prefer, you can also answer to these questions in French on our forum ;-) => forum.glx-dock.org )

@Guy Roche: I post here your answer because I'm not the only one people who can help you ;-)

Hello Mathieu,

To this problem, I was trying to resize nautilus window, because since about one month, it's impossible to resize window. Only full screen or a little, too little window. No problem with others windows.
I use cairo dock because i cannot "regler" colours (gamma, ....) of my pc (DV7 2200SF HP) With cairo, I can. Unity seems to be "compliqué" like windows 8 with their "tuiles". 8.1 is better with the classic menu. It's better for me using classic "menus" Always when their is much windows open and then I use "copy/paste".
 (by the way, I boot on the same disc (320GB) Ubuntu 14.04 , Win 8.1 and Win7. Windows is only for videos (making dvd) and now, win 8.1 for applys. On ubuntu, I use to VirtualBox (the new version of VB (virtualbox-4.3_4.3.10-93012~Ubuntu~raring_amd64) don't works ! dependance pb And on VB : Win7 to use videos making dvd, captv, ... And Android 4.4 to use somes prefers applys.
So, pb with cairo : I think that I click too much trying resizing windows and I use too a weather conky: This conky goes to internet searching meteo datas and picture of satellit every 13 min and picture is putting then on desktop. A very pleasant prog and much "pratique". I can send you more infos if you want. (see pce jointe)
As I can tell you... Another thing : Are you working on a desktop that can use Classic menus, Applys like Android (Android is too on linux) And finally it will be fun to find our phone directly on our pc (all media inter connected simply without cables). There is some applys very good like "marmiton", Metropolis (film an "horaire des seances de cinema"), ... Without using a browser (or "transparent") like microsoft begin to do. an icon and ...> apply comes without enter command line on browser or...

A+

About this specific problem with Nautilus, it should be better now. The latest version of Nautilus has been modified to have a better integration (only) in Gnome-Shell session but the behaviour is now broken on other sessions... except that Ubuntu devs have patched Nautilus to be used in all other session and now the dock should use this patched version :-)

> It's better for me using classic "menus"

I agree with you :-) I like our classical applications menu with the search feature :-)

Thank you for these ideas!
You should no longer have this crash with the latest version of Cairo-Dock. I'm going to close this bug report but feel free to reopen it if you still have this crash.

PS: for you problem with VirtualBox, according to the version number, you're using a version for Ubuntu 13.04 and you're using Ubuntu 14.04 ;-)
You can add the repository made for Ubuntu 13.10, it's maybe better than the other one:

  $ sudo -v && echo "deb http://download.virtualbox.org/virtualbox/debian saucy contrib" | sudo tee -a /etc/apt/sources.list.d/virtualbox.list && wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add - && sudo apt-get update && sudo apt-get install virtualbox-4.3
