That appears to be the case.

Based on the stack trace, the problem is the
MySql.Data.MySqlClient.MySqlConnection constructor, which explicitly
uses C:\output.log.  Either MySql.Data.MySqlClient.MySqlConnection has
this hard-coded, or MySql.Data.MySqlClient.MySqlConnection is reading
some config file to get this filename.

Either way, you'll need to talk to the MySql.Data maintainers. :-(
