Yes, dyslexia. I have been using g3. So the typo was in the bug report.

If the command format is ... g3:outputfile, then the "g3:" is syntax, not 
filename. While Debian Linux will allow a file name like"g3\:name" (which is 
how it displays it, not much else will correctly save a file that way. Anyway, 
if I want that, I will type ...g3:g3:.... and may the lord have mercy.

conver infile -fmt g3 outfile, I'm cool with that. Just let us all know.
