Install with Mu can't find wp_die if a database error occurs

[jmdh]

Reproduced in 2.9.1.1 (latest Mu release).

As discussed in ​http://mu.wordpress.org/forums/topic/16409
if a database error is encountered during the initial install, the following error message is displayed:

Fatal error: Call to undefined function wp_die() in /usr/share/wordpress-mu/wp-includes/wp-db.php on line 1147

Note that there is no Mu component and neither is the 2.9.1.1 version listed in this trac but ​http://trac.mu.wordpress.org/ tells me to report here.

In fact, I now see that the problem looks like it's been fixed in changeset 2071 in the mu subversion but in case anyone else ends up digging around, this bug report may be useful.

Will be fixed in MU 2.9.2, which I believe is at RC stage right now.
