I'm not sure this is a duplicate. The parent thread is about UbuntuOne, which I don't have installed.

I got this:
Jul 10 14:46:39 dubuntu kernel: [ 152.470336] nautilus[5191]: segfault at 0 ip 00007fff7ae65bed sp 00007fff973e6770 error 4 in libnautilus-dropbox.so[7fff7ae62000+8000]

while moving ~200MB of files from my desktop to a SMB share. Dropbox was not involved in the action.

[Youresorock (youresorock)]

It did the identical thing when I first unloaded dropbox and then tried to do the copy.

Jul 10 14:58:36 dubuntu kernel: [ 869.178820] nautilus[9060]: segfault at 0 ip 00007fab2491ebed sp 00007fff3d62e3c0 error 4 in libnautilus-dropbox.so[7fab2491b000+8000]

[Christian Rudh (crudh)]

Same problem here when copying files to SFTP-mounts. And it only happens for some of the mounts, but for those every file copy causes the crash. It worked fine when upgrading to Karmic, but started to happen directly after installing Dropbox. No dropbox-share was involved in the file copy.
