[Xastir] Received station packets causing Xastir to crash

[John Hartman]

I am running Ubuntu 10.04 and Xastir 2.0.1 and have a problem with
Xastir crashing after receiving packets from a specific station.   

I discovered this by running Xastir from terminal mode and turning on
the debug level (to 1) in xastir,  The crash always seem to occur right
after processing traffic from a specific station. Is there some setting
I've missed that will let me block this station.  

All help appreciated.  

Is there a way to block the offending station?
