Comment(by fwendt):

 I can trigger this under FSO. Every time a GPRS connection is closed down,
 or an attempt failed quite late (after ppp0 is setup I guess), I get
 unregistered signals on the system dbus.
 I estimate that it takes some 15+ seconds after the connection is shut
 down until I get the dbus signal.
 This also happens without me doing anything to the phone, but I haven't
 logged that or looked into it - I've just noticed at work, looking at the
 screen from time to time, that the signal strength bar goes from 80-85% to
 0 and stays there for quite some time. I've also been forced to reboot to
 get a signal back. (Don't know what to try else but /etc/init.d/frameworkd
