There was some change recently in the tray backend to use a "new" one by 
default:

 From a quick look at the code there seems to be a way to force the 
"traditional" backend by using LAZUSEAPPIND=NO environment variable, so 
try to launch your program as

   $ LAZUSEAPPIND=NO ./yourprogram

...and see if that fixes it. If so then it might be a bug in the app 
indicator backend or an issue with Cinnamon's app indicator 
implementation (i remember reading it had some issues some time ago).
