[Xastir] png snapshot problem

[N1OFZ]

First off 1.2 is great.  Much more stable than 1.1.5 was for me.  The 
only problem I have is now that I have upgraded three machines I have 
realized that if I enable png snapshots I immediately get the following 
error:

Xlib: sequence lost (0x1402ff > 0x130598) in reply type 0x2!
X Error of failed request:  0
   Major opcode of failed request:  123 ()
   Serial number of failed request:  1276894
   Current serial number in output stream:  1246616

And Xastir dumps.  Any ideas?

Thanks,
Dana
