[mikael]

Hello,

I can't have quota with dict working... In my error file, i have a 
"killed with signal 11". I don't know if it's a bug or a bad dovecot 
configuration... I hope i'll give you enough informations that you can 
help me... (sorry for my very bas english ;p)

==> Information about MySQL :

I have created a "dovecot" db with a "quota" table, and a "dovecot" 
mysql user with all rights access on the "dovecot" db. I have one line 
in my "quota" table :

path | username | current |
??   | myuser   | 1024    |

(I don't know what to enter in "path" field...)


==> Core dumps

I have try the "Core Dumps" procedure, but i don't know if it's a 
success... There is what i get :
