Just an update.
Ok, this time (all the 16.5 and above) modest-home-applet stayed.

I noticed there is a
maemo-geolocation 1.1.3-1
on the Extras.
Whats the difference to the one which keeps getting removed with CSSU updates:
microb-geolocation 1.1.5-6+0m5?

btw: I pinned rtcom-accounts-voip-support with priority 500 since it is getting removed with CSSU updates. Without it I noticed I am able to log in to my Router (=providing SIP on my regular phoneline) but all calls in our out get instantly cancelled.
