Code review comment for lp:~karl-qdh/indicator-datetime/sniffles

You need to check that evolution is installed before you enable the items. It's ok not to update that when it's installed after the indicator has started or if it gets uninstalled though.

There is an example for that at: http://bazaar.launchpad.net/~indicator-applet-developers/indicator-me/trunk/view/head:/src/me-service.c#L251
