I was surfing the web looking for dumb stuff and ran across the Brawndo site. Noticing that a new logo was available, I quickly downloaded it and observed that the Dock proceeded to crash, restart, crash, restart, and so on. Thinking it was just another temporary “Leopard has gone batshit insane” moment (I’ve experienced more than a few of these), I rebooted the box. Imagine my surprise when after rebooting, the Dock continued to crash and restart.
First order of business: stop the Dock from crashing. I headed to the Dock.app folder and renamed the executable within to Dock.old. After doing this I was finally able to attach gdb to it and grab a backtrace from the crash:

Hmm, I see Quicklook and some Quartz jpeg loading stuff in there. Wonderful. Time to use fs_usage and see which file was causing the grief.
“brawndo_logo.jpg”
No way. This is just too funny. Filed as bug rdar://problem/5657300. Head to the brawndo site to download the file for yourself, if you dare. Anything which uses Quicklook to generate image thumbnails will crash and burn on this file.
Postscript: I realize that this is probably a Quartz issue - however Safari doesn’t blow chunks when it tries to load the file and I’m not going to dig any deeper.
Post-postscript:Wolf dug deeper.

That image was generated from Adobe Illustrator 13.0, and the original artwork is a composite of vector shapes with a raster texture over it. I wonder if there’s something odd with the way Illustrator writes JPEGs.
