Hi David,

The error message "crashed on signal 11" basically means the program
went off into never-never land.  The PID (process id number) should
reference which program crashed -- is there a message about starting
a process with that PID in the log?  i.e. what program is being run there?
Also are the other messages preceded by some indication of what
program is finding these errors?

You might also try some other file formats like a tif file.  Make sure
its a grayscale, 8bit file and that you select the QTR mode.  You can
also try printing without a curve -- it ought to print thru gimp-print
in the normal mode.
