Hello I'm having the exact same problem as Sam Davies, right after opening a folder with a avi file in it, the memory usage for nautilus goes to the roof. And I don't know if is the thumbnailer, because the second time I enter the folder (the thumbnail was alredy on cached) and the same thing happened.
I attached a screenshot of this problem happening on my computer, which by the way is: AMD Athlon 64 3000+ 1GB Ram Ubuntu Hardy Heron 8.04 ** Attachment added: "Nautilus Memory Problem" http://launchpadlibrarian.net/13970504/NautilusLeak1.png -- nautilus memory leak https://bugs.launchpad.net/bugs/204413 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
