Yes, I suspect that's it.

I'm more than halfway through a rewrite of that code.  Currently, the
Xpm code takes the pixmap and converts it to an .xpm which is written
to disk.  Next, a system() call is made to the ImageMagick convert
program which converts the .xpm to a .png which is also written to
disk.

While diagnosing this problem, I replaced the system() call with
ImageMagick code which performs the conversion.  I got the same
errors, which is good in this case.  I'm now more than halfway through
replacing the Xpm code with more ImageMagick code.  Once that's done,
the process will be much improved.

Jack.
