#2196 Edit disk quota in webmin error

[Anonymous]

Webmin 1.220+Trustix3.0 (kernel 2.6.11.12)
File system ext3
Edit the quota is impossible, the news values are'nt
saved.
there is no error on the screen

But when i edit the quota in a shell, it's works and
webmin can see the new values but not modify it...

ps:Why There is no quota with reiserfs ??

Thank
Laurent
