I am also experiencing this problem. It seems that Gnome now requests 256px thumbnails instead of the former 128px.
The thumbnailer from sourceforge.net (last updated in 2005) that Ubuntu packages seems to cope very badly with the sizes bigger than 160 (the exif thumbnail size). Ubuntu should switch to gnome's thumbnailer, which is based on libopenraw: http://libopenraw.freedesktop.org/wiki/RawThumbnailer/ This one rotates thumbnails and is much faster. You will be able to close at least 3 bugs at once by swithing the implementation. Please, stop packaging this old stuff from sourceforge. BTW, here is a bit improved version of the gnome's thumbnailer: https://github.com/angryziber/gnome-raw-thumbnailer -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256639 Title: Gnome Raw Thumbnailer is very very slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-raw-thumbnailer/+bug/1256639/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
