Maybe this issue is somehow related to WLAN becoming just connected. Do you know how good your signal is to the WLAN? Does your phone get easily disconnected? I wonder how Telepathy reacts if the connection is disturbed. Will it persist the mode that was set, and apply it when connection is back on, or does it just fail? Also do you have the "restore previous availability" option on? I notice something a bit strange on the log too before the error: ConditionManagerLocationCell::monitorCellId(0) This means that there is no GSM signal.
