I'd say InstallationIssue, but that's just a guess…

And as I see 0.10-stable here, let me say that if 0.10.x is no longer actively maintained, doubly so for MySQL on 0.10.x!

MySQL support has been much improved in 0.11, so if you want to use that database backend, an upgrade is highly recommended. See MySqlDb for the proper charsets and the engine that must be used.
