Package: mysql-server-5.5
Version: 5.5.33+dfsg-0+wheezy1
Severity: normal

Dear Maintainer,

I am in the habit of using  mysqlhotcopy  for backup, something like
  mysqlhotcopy "--regex=.*" ./tmp
After the upgrade from squeeze to wheezy (mysqlserver-5.1 to 5.5), that
fails with error
  DBD::mysql::db do failed:  command denied to user 'root'@'localhost' for table 'cond_instances' at /usr/bin/mysqlhotcopy line 520.
Googling for similar, I came across
that says to skip database
(as well as information_schema already skipped in mysqlhotcopy).

The following one-line patch seems to have solved the problem for me.

Cheers, Paul
