[Gimp-user] Problem with gmic-gimp

[serge bouc <serge bouc free fr>]

Hi everybody,

   I am running Gimp 2.6 on Ubuntu 12.04. I use Gmic 1.5.6 without problem,
but recently I tried to install version 1.6.8, and it doesn't work : I 
see GMIC in
the menu, its dialog opens, but any filter I try ends the same way :

"The plugin Gmic-Gimp crashed. Gimp might be corrupted, save your work 
and restart".
(sorry for the approximative translation from french... :-[ ).

I tried to remove the old version of Gmic from any place I could find 
it, and place the new one
either in my personal folder or as a global install, without success. I 
also ckecked that the
required libraries are present.
   Is this a problem of incompatibility of Gmic 1.6.8 with Gimp 2.6? Am 
I missing something?
Any suggestion would be welcome. Thanks a lot in advance.

Serge.
