I have some problems with Trac 0.10b1 and MySQL 4.1.11-Debian_4sarge5-log.
When I try to use a database with collation "utf8_general_ci" with trac-
admin, I get the following error:
{{{
Failed to create environment. (1071, 'Specified key was too long; max key
length is 1000 bytes')

}}}
So, using collation "utf8_general_ci" trac-admin cannot create the
environment. However, using collation "latin1_general_ci", trac-admin is
able to finish it's work.
But: while viewing tickets, I get the following error:
{{{

raise errorclass, errorvalue
OperationalError: (1267, "Illegal mix of collations

}}}
To summarize:
* latin1_general_ci: I can create the environment but I cannot view
tickets
* utf8_general_ci: I cannot create the environment
