Thanks, this looks better and I indeed think it is important. The "del ..." line looks ugly.

I'm using Python 2.7.10, but this also works there, so, I replace it with your suggestion.

And before you tell me that python 2.7 is old, the thing is that I'm writing a pluging for Gimp and this is the version they distribute :-(

Thanks for your valuable help

Best regards
