[Xastir] PNG snapshot problem

[Chris Hare, KD5WIM]

Well, not quite.

convert is happy -
I can convert JPG to PNG
I can convert PNG to XPM
I can convert from XPM to PNG

I have one snapshot actually created late last night, but each time I
turn on PNG snapshots, xastir crashes.

Here is my .xastir/tmp directory 
[chare at zeta .xastir]$ cd tmp
[chare at zeta tmp]$ ls -l
total 6868
-rw-rw-rw-    1 chare    chare       47712 Oct 10 22:51 map.gif
-rw-rw-rw-    1 chare    chare      594786 Oct 11 15:18 map.jpg
-rw-rw-r--    1 chare    chare     3278037 Oct 11 21:35 map.png
-rw-rw-r--    1 chare    chare     2497884 Oct 11 21:37 map.xpm
-rw-rw-rw-    1 chare    chare      585867 Oct 10 23:58 snapshot.png
[chare at zeta tmp]$

On the XPM files created by convert, the last line is a 

};

So, I am not sure what the problem is.  Is there some form of logging I
can enable?
