[2.6.35-rc6+] zsh: corrupt history file /home/wfg/.zsh_history

Hello,

After upgrading kernel, I got this message on every boot: 

        zsh: corrupt history file /home/wfg/.zsh_history

The .zsh_history seem to always contain some rubbish text/binary
viminfo data. The content is different on each boot. Last working
kernel is 2.6.33. The kernel is built from Jul 30's Linus tree.

$ grep /home /proc/$$/mountinfo
