Unhappy Missing dock and background flashing on Mavericks GM

I just installed the GM from Mountain Lion (no previous DPs). When it rebooted after the install, I had no dock. I rebooted and still no dock, but now the desktop background flashes with about 1 second intervals between my background and a solid light gray color. Rebooted a few more times and it's a toss up which I get. Has anyone seen this or have any ideas for a fix?

Checking the Console, I see that the Dock app is crashing repeatedly when the background flashes. When the background stays like normal, there's nothing in the Console, however Dock shows up using 100% CPU. I created a new user account and I can log in fine with it, so it's something specific to my account I'm guessing. That's all I've been able to figure out so far on my own, and haven't found a single page on any forums of anyone seeing anything similar.

Next time I install on my backup machine first, then my main one :/

Have you looked on the Developer forums to see if it is happening to anyone there?

Is that really necessary? ().

OP, it's good that the dock appears normal in another account, because that means it's probably not a problem with your installation. What software do you have on your computer? Any system utilities that might be causing a conflict?

I obviously felt it was or else I wouldn't have used it.

open terminal and enter:

#cd /Users/*YOUR USERNAME*/Library/Preferences/
#rm -f com.apple.dock.*
#killall Dock

You'll lose your icon order, but it's the first thing I'd try. You could also just copy/rename the plist so it's non destructive.

This was one of the first things I tried thinking it would help. I even went as far as removing all com.apple.* preferences in case it was something else, but I was still getting the same errors.

I woke up this morning to start fiddling with it again, and it's suddenly showing up. I'm afraid to reboot now in case the problem comes back, but I'll reboot tonight just to be sure and report back what happens in case anyone else runs into this.

Fixed!

If anyone else has this problem and stumbles upon this post you just need to delete the system config files which are in user/library/preferences:

Preferences/com.apple.spaces.plist
Preferences/com.apple.desktop.plist
Preferences/com.apple.dock.plist
Preferences/com.apple.dock.db
Preferences/ByHost/com.apple.screensaver.NUMBER.plist
Preferences/ByHost/com.apple.dock.NUMBER.plist
