Fix #51187 on bugzilla of ximian If "alarms" or "alarms->alarms" is NULL
2004-03-18 Alfred Peng <alfred.peng@sun.com> * Fix #51187 on bugzilla of ximian * gui/alarm-notify/alarm-queue.c (query_objects_changed_cb): If "alarms" or "alarms->alarms" is NULL after querying a calendar for the alarms of a particular object, the reuse of "cqa" will probably cause evolution-alarm-notify to crash. So remove "cqa" when "alarms" or "alarms->alarms" is NULL. Otherwise update it. svn path=/trunk/; revision=25112
