test main.create is failing on my 11.04 machine as follows:
main.create [ fail ]
drizzletest: At line 1187: query 'create database имя_базы_в_кодировке_утф8_длиной_больше_чем_45' failed: 1006: Can't create schema 'имя_базы_в_кодировке_утф8_длиной_больше_чем_45' (errno: 36)

The result from queries just before the failure was:
