Ok, I think I've got the problem figured out now. The station that 
deleted the object sent only a kill packet, no "adoption" packet 
(identical packet with its own callsign) before that. Or maybe it sent 
an adoption packet, but my station never received it.

When the kill packet was received, Xastir deleted the object from the 
map screen. But it did not touch the objects.log file, the original 
object sent by my station was still there in its original "live" form. 
My Xastir continued to send the object kill packet for a while after 
receiving the kill packet from the other station that only sent one kill 
packet. I don't known whether this is intentional or a bug, in this case 
it was good as the killing station only sent one packet and it might not 
have been heard by everyone (or maybe it stopped sending the kill packet 
because it heard my Xastir send kill packets).

Then when I restarted Xastir a couple of days later, Xastir read the 
object log on startup and started sending the object as live.

I glanced through the object part of the APRS pdf spec and there was no 
explicit mention on adopting an object before killing it. Is this what 
Xastir expects a "killer" to do? I wish Bob could get those errata pages 
of his wrapped into a new PDF revision.. I haven't checked the errata 
pages whether there is more information on this.

I'm running a CVS version of Xastir compiled on January 5th.
