No longer fetches from inbox

Recently (a few weeks back) gm-notify has stopped working.

I'm running a fully updated Ubuntu 14.04 64 bit version. "uname -a" output :

Linux my-PC 4.4.0-53-generic #74~14.04.1-Ubuntu SMP Fri Dec 2 03:43:31 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Executing the program from terminal shows this :
