Yes. If I navigate with gthumb in feisty to a directory that only contains eg. feisty-desktop-i386.iso (herd 4), a single icon representing the .iso file is shown in gthumb, and at least when I click once on the icon gthumb freezes while gthumb's mem usage raises to ca. 600MB - manageable with 1GB of memory and takes only 5-10 seconds, but had I a bigger iso file or less memory I'd be in trouble. After the 5-10 seconds memory usage is back to normal.
gthumb 3:2.9.1-0ubuntu2 / amd64. ** Changed in: gthumb (Ubuntu) Status: Needs Info => Confirmed -- gthumb eats all memory when clicking on a ISO file https://launchpad.net/bugs/48655 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
