Comment 4 for bug 261587

I've run through the installation a couple of times on my system. Nothing calls into the offending function when I install. Weird. I can't reproduce the problem.

Can you tell me ... when you see this error message, whether you had already reached the page asking for database details (ie. database name, user, password)?

And this is probably obvious, but I presume you've tried this more than once and it happens every time?

I don't suppose you have a database lying around on your system with the following details:

User Name: username
Password: password
DB name: databasename

by any chance? These are the settings in the settings.php file before installation, which normally aren't supposed to be valid.
