NetworkManager not working when logging in via fingerprint

[Fibonacci]

I've recently noticed that whenever I log in via fingerprint reader (AES2501), my system behaves strangely.
For example, the Gnome panels take almost a full minute to appear after everything else has been loaded, and there's no NetworkManager icon in the panel - even though nm-applet (and thus NetworkManager) is running as shown by top; that can be (partially) solved by killing NetworkManager, restarting dbus, and then manually running NetworkManager.
None of that happens when logging in using a password.

Judging from your description, I am going to assign this bug to the “libfprint” package in hopes that it will have a faster response. If you believe that I have chosen the wrong package, please change your bug to the correct one. Good luck on getting it fixed!

The device you have is supported by the latest driver in libfprint0:

Could you install the latest version from the fprint PPA, as described here and report back your results:

The NetworkManager issue appears to be solved now, but the Gnome panels still take longer to appear than when I log in via password.
