Oh, there's another reason for not loading all of Krita in the thumbnailer -- it would mean that any application that opens a file dialog will load all of krita. All the resources will be loaded as well -- it's the reason the kimgio plugin relies exlcusively on the mergedimage.png now. - Boudewijn ----------------------------------------------------------- This is an automatically generated e-mail.
