Same crash while installing Ubuntu 11.10 beta 1 in a VMWare with 1900 Mb Ram, all others are default settings. Host OS is Win7.

/var/log/syslog also contains reference to this LockFailedException:

`ubuntu-bug ubiquity` opens this bug report in the browser after having displayed an exception, not really a part of this bug report but might hint to some missing info maybe?

ubuntu@ubuntu:~$ ubuntu-bug ubiquity
