I was trying to upload the gif image I downloaded from http://www.iglesiauruguaya.com/noticeu/mapa_ceu.gif, but the upload lasted quite much, and then it said: A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "LocalFile::upgradeRow". Database returned error "1205: Lock wait timeout exceeded; try restarting transaction (localhost)". Another person could reproduce the same on the same mediawiki site.
It looks like you're reporting a bug about a specific mediawiki installation, not mediawiki itself.
