/sbin/lvm - Parse error at byte 67 (line 1): unexpected token

After the upgrade to oneiric beta lvm stops to work:

[root@nogrod ~][0]# /sbin/lvm
  Parse error at byte 67 (line 1): unexpected token

After running strace it turnded out that there's a problem with a file:
/etc/lvm/cache/.cache
(it's content)
/lib/modules/2.6.38-11-generic/kernel/drivers/usb/host/xhci-hcd.ko

Removing of a file fixed the problem.

I'm not sure what is that file and when it was created, shouldn't it be removed during the upgrade?
