Comment 10 for bug 1388130

Still no solution, but I've at least (hopefully) eliminated some more variables.

As I know this problem doesn't currently exist on Vivid, I tried back-porting `network-manager` and `network-manager-applet` from Vivid, but no luck... same problem still exists.

And on the off chance that this is kernel-related, I also tried the 3.16 kernel on Trusty... but connecting to WiFi still works fine, so it doesn't seem to have anything to do with the kernel version.

However, I have noticed some differences in the Dbus processes running an a system with Nvidia hardware vs a system with an Intel GPU, so I'm further investigating that today...

Also, I'm not that familiar with network-manager, so if you have any advice for how I could get you better debugging information, please let me know!
