MySQL Bugs: #53664: Access Denied for User XXX / Could not retrieve user privilege information

Bug #53664	Access Denied for User XXX / Could not retrieve user privilege information
Submitted:	14 May 2010 21:55	Modified:	15 Jun 2010 7:41
Reporter:	Patrick Bertsch	Email Updates:
Status:	No Feedback	Impact on me:	None
Category:	MySQL Server	Severity:	S1 (Critical)
Version:	5.1.41	OS:	Linux (Ubuntu 10.04)
Assigned to:		CPU Architecture:	Any
Tags:	mysql-admin, No Privileges

Description:
Tools like MySQL-Query-Browser and Emma tell me that Access is denied for this user and this Database but I'm connected with this user to the Database.

When I try to check the User Privileges with MySQL-Admin Version 1.2.12 I get the Messagebox "Could not retrieve user privilege information.", which I thought was fixed a long long time ago. I hope some can help me.

Thanks in advance,

   Patrick

How to repeat:
I'm not sure how I did it but I started the MySQL Server and tried to load data from a csv file into my existing database. 

A day before all worked fine.

LOAD DATA INFILE '/home/patrick/data.csv'
INTO TABLE 'test'
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n';

Please, connect as usual and get the results of:

select user(), current_user();
show grants;
