Description:
Upgrading from 4.1.0 to 4.1.1 via rpm -Fvh or rpm -Uvh can leave the user in a
state of confusion if they try to use SHOW GRANTS. There appears to be an
incompatibility somewhere in the code that prevents a 4.1.1 server daemon from
reading the 4.1.0 grant tables properly - or the error message is just
unclear.
See the 'repeat' section for some logs of a tested upgrade process. It pays
to have good documentation on what the user/password combos are. A diffed
mysqldump from before and after the upgrade revealed no changes to the mysql
tables.
How to repeat:
rpm -ivh MySQL-server-4.1.0-0.i386.rpm MySQL-shared-4.1.0-0.i386.rpm
MySQL-devel-4.1.0-0.i386.rpm MySQL-client-4.1.0-0.i386.rpm --nodeps
(--nodeps to work around that silly libcrypto issue on RH 9+ systems)

Suggested fix:
Report a useful error, such as 'Grant is in an invalid format. Re-issue the
grant.'
