Comment 13 for bug 438463

I can confirm that it allows epiphany to startup fine. This bug reappeared after I had worked around it and without the libcanberra-gtk-module package it does indeed start up. The following warning is generated but it looks like it's because I started epiphany with the package installed to confirm that I got the 'Bad Window' error (which I did) and then uninstalled the package to then run epiphany which did start up:

Gtk-Message: Failed to load module "canberra-gtk-module": libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
