vmysql sql error

[Lucas]

Hi,

I have this error:
vmysql: sql error[5]: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
when access to "show users".
Rest of funcionalities works as expected.
Vqadmin version: 2.3.2 or 2.3.6
Mysql version: 4.1.11 and client libmysqlclient.so.14
Vpopmail version: 5.4.0

Any clue?

Thank you in advance,
Lucas
