Comment 0 for bug 1178098

Not clearly a dupe, it appears.

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!
