App Store crashes when I log in or log out

[echo.park]

Hi,

everytime I log in or log out, the App Store quits itself.

Console:

When I log in using the "Purchased" tab ("to see your purchases you need to log in"), it's all fine.

Who can help? I don't know what this is due to the fact I did a clean install already, for anothher reason though. Problem is not solved.

There has already been a post about this already. I do believe it is a wide spread problem, that most people don't realize unless they are logging in or logging out of Mac App Store. If you notice, when installing Mountain Lion, you put your Apple ID in while installing. No one usually logs out of Mac App Store unless there is more than one user.

Here is the MacRumors forums link of the post already about this.

Also, here is discussion in Apple's own forum about this subject.
