I'm trying to install copy.com's client on Ubuntu 13.10 but when I do, I get the following error message:

Gtk-Message: Failed to load module "canberra-gtk-module"

(CopyAgent:4430): LIBDBUSMENU-GTK-CRITICAL **: watch_submenu: assertion 'GTK_IS_MENU_SHELL(menu)' failed

From there, it initially appears that the Copy client installs correctly. I am prompted to login and their icon shows up in the task bar. However, sync does not work properly. Items placed in my Copy folder on other devices (or through the web interface) sometimes download to this machine, and sometimes don't.

I have investigated the first error message and found this solution, that I should install the libcanberra-gtk-module. But when trying to install it, it is already installed. Just to be sure, I reinstalled it but it seems to have had no effect.

I attempted to investigate the second error message and found that lots of different programs give similar error messages, but all of the solutions I could find seemed to be specific to the program that was under discussion on that particular thread.

Any thoughts on how I could solve this? Or at least what I can try next?

  • Do you still have this problem? – Elder Geek Apr 29 '15 at 14:10
  • @ElderGeek No, but I don't recall what I did to fix it. Sorry. – jimchristie Apr 29 '15 at 14:47

This appears to be a long standing bug and was not considered critical see post #3: https://bugs.launchpad.net/ubuntu/+source/libdbusmenu/+bug/953158

  • This is a nice description of the binaries, but the post does not answer the user's original question: how to solve the error message issue? – PJ Singh Apr 29 '15 at 1:13
  • @PJSingh added more info after further research. – Elder Geek Apr 30 '15 at 22:07
