Hi,

I've just installed Mediawiki with sqlite support and I got the following error when trying to create a new user account:

Fatal exception of type MWException

Enabling $wgShowExceptionDetails, I get the following instead:

User::addToDatabase: hit a key conflict attempting to insert a user row, but then it doesn't exist when we select it!
Backtrace:
#0 /var/www/localhost/htdocs/mediawiki/includes/specials/SpecialUserlogin.php(468): User->addToDatabase()

#9 /var/www/localhost/htdocs/mediawiki/index.php(59): MediaWiki->run()
#10 {main}

This is my actual configuration:

Mediawiki - 1.21.2
SQLite - 3.7.17
PHP - 5.5.4

Any clue what might be causing the problem?

Couldn't reproduce with MW 1.21.2, sqlite 3.7.13 and php 5.4.4... trying php 5.5

Could you file a BUGREPORT?

Done! => Bug#55552

I have a similar or same bug, but with PostgreSQL 8.4.9. See Bug#55552.
