For sometime now (a week or so) I have been fighting with Nautilus. I
discovered that any time I navigated the 'Downloads' folder, Nautilus
will hit 80-120% CPU usage ... and freeze the Desktop. SIGKILL-ing
Nautilus became a routine so I filed a bugzilla report.
In the end, the culprit was:

Turns out the SVG renderer was having trouble creating a thumbnail from
our Design file. Actually, Inkscape had its moments of *Argh*. The Bug
tracking guys are requesting an attachement of this file so they can
track the bug further. I hope this is okay.
