bug#47482: GIMP: GEGL issue

[Tobias Geerinckx-Rice]

Don,

I know I said I wasn't going to bother investigating but I 
couldn't resist :-)  It was too ‘fun’: it only happens if you 
didn't have graphviz installed, such as when running the GIMP in a 
--pure environment, and the error message is worthless.

I added a reference from gegl to graphviz in 
7162e5b88208d00188dd9c7b22e0fcde2871fb55.

Kind regards,

T G-R
