[Gimp-user] Batch mode: "batch command experienced an execution error"

[David Chan <cbsa03 bangor ac uk>]

Hello,

I can't get Batch Mode to work on Ubuntu 12.04. I follow the 
instructions in the tutorial:

  http://www.gimp.org/tutorials/Basic_Batch/

But I get an error "batch command experienced an execution error". Even 
if I use --verbose there are no more details. Is there any way I can get 
a more detailed error log? (Or does anyone know what the problem is 
likely to be?)

If I just do "gimp -i -b '(gimp-quit 0)' then it successfully starts 
and exits.

Example shell session transcript:

david dl:~$ wget -q http://troi.org/hello.png
