[kronolith] Alarm on kronolith doesn't work

[Marco Maiani]

I've installed Kronolith 1.1.2 for Debian and everything works well. 
Yesterdays I discovered that Kronolith alarm doesn't work. At the hours 
I setted kronolith to have alarms for some events, simply nothing 
happens: no pop-up, no sounds, no e-mails. Nothings happens to remember 
the event. Do I need to configure something in somewhere files?
