Could this be a duplicate of https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/774096 and https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/774395 ?
I don't see the XSession errors Ben Stanley reported though... But I think they might be unrelated. What I do get is the following in dmesg: gvfsd-ftp[10868]: segfault at 0 ip (null) sp 00007f26168bbd88 error 14 in gvfsd-ftp[400000+30000] -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/778176 Title: Nautilus freezes on FTP file transfer -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
