        That is what I figured. Since I was able to create and 
   manipulate the file to start with, I assume it is something
   that I changed. Problem is, I don't see that malloc() returns
   a useful error indication.

        I have the cache size set to 1024MB, and from what I can tell,
   no tile cache is actually allocated (at least, I don't see any
   fluctuations in the disk usage. Which means I have enough memory
   or it is being buffered, or both, or somehting else.)

        Top reports somewhere in the vicinity of 550 - 600MB of memory
   is being used. GIMP and this file is a great way to move memory
   from "inactive" to "free". :-)

        Is there a reasonable way to provide more detail as to what
    GIMP is doing in a bug report? Reporting that GTK is failing
    when a 45MB jpg file is expanded to 500MB+ is perhaps a bit too
    generic. It would be nice to say it was in routine XXXX.

        Also, I would like to verify that I am not exhausting kernel
    memory for some reason.
