Comment 37 for bug 711429

Now got this crash again. Twice, actually; I'm thinking I can reliably reproduce this on Precise. The steps I followed:

1.) Open Nautilus and start in your home folder.
2.) Hit Ctrl+H to show hidden files and folders.
3.) Navigate into ~/.hedgewars/Demos and copy the replay file(s) in there (this assumes Hedgewars is installed and you have available game replays; more experimentation would be needed to see if other files/folders can be used instead).
4.) Navigate back to the home folder and hit Ctrl+H again to hide hidden files and folders. Go into the ~/Ubuntu One folder.
5.) Attempt to paste what was copied into there.

The theme will revert to standard GNOME and Nautilus will close; the paste operation will not occur and an Apport window will come up.

A side effect of this crash is that once Nautilus has been triggered to crash like this, it is seemingly impossible to start it again without a reboot, as any attempt to start it will fail and a gnome-settings-daemon Apport crash window will come up instead. This basically breaks graphical file browsing on the user's system.

Note too that at step 4 above the files are specifically pasted into the Ubuntu One folder. Although I have not experimented with it much, it appears that pastes elsewhere (i.e., the desktop) still work just fine and don't cause any issues.
