Bug Description
Not sure if I should go ahead and change this to a nux bug, instead of compiz, from the stacktrace. But I'm sure those who know better will sort that out easily.
I opened the dash, via the keyboard, then opened a preview of a file, also via the keyboard (the menu key). I wanted to open the folder the file was in, rather than the file directly. So in the preview, I tried to keyboard-navigate to do that. I tried a few keys, like Tab and Shift-Tab. I can't recall what key I hit first; I couldn't tell for several seconds that compiz had locked up, and I was trying a few different keys.
I haven't tried reproducing yet, 'cause I've barely got time to write this up; no time to trigger another crash.
(An aside: I know compiz will be supported in LTS releases for a while, but still I'm not sure how much attention may go to compiz issues, now that it's deprecated for a future of Mir. Any comment on bugs like this, in general, is welcome.)
Thanks!

Confirming. To reproduce:
1. Open a preview
2. Press Shift-Tab
3. Crash
The crash might occur at the first try or it might take few presses (seems to depend on the amount of buttons in the preview). Also app previews don't crash when Shift-Tab is pressed but the functionality (move focus to previous button) is broken...
Marking this as an Unity bug for now...
