Got the same problem (also on Ubuntu Edgy). I started noticing this problem after the following updates (and a reboot):
libnautilus-extension-dev (2.16.1-0ubuntu3) to 2.16.1-0ubuntu3.2 libnautilus-extension1 (2.16.1-0ubuntu3) to 2.16.1-0ubuntu3.2 nautilus (2.16.1-0ubuntu3) to 2.16.1-0ubuntu3.2 nautilus-data (2.16.1-0ubuntu3) to 2.16.1-0ubuntu3.2 popularity-contest (1.33ubuntu2) to 1.33ubuntu2.3 update-notifier (0.43.2) to 0.43.4 Oh, and I had just installed Beagle from http://beagle- project.org/files/ubuntu/edgy/ ** Attachment added: "crashlog" http://librarian.launchpad.net/6936377/_usr_bin_mono.1000.crash -- Mono craches at Nautilus start. https://launchpad.net/bugs/90364 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
