Hi, not sure I should post this to the list, but I figured it wasn't worth a whole bugreport.... Using the image http://home.student.utwente.nl/p.e.c.melis/mannetje.xcf I get an "initial_sub_region:: error :: src->w * (src->bytes + 1) > 512" from the gimp, when I click the navigation icon of the window it's loaded in. Quitting the gimp and reloading does not solve the problem. I did not do anything "special" to get this image, just some layer manips and filters. Gimp version is cvs of 3-12 (post 1.1.29) Bye!
