Detected on modoboa 1.0.0

While trying to add a new filter the dialog doesn't show up. Digging deeper this is the traceback on the server side:
Internal Server Error: /sfilters/vari/newfilter/

It appears that the server fails at listing my mailboxes which are quite many, but the listing on the webmail works without any problem

Hi,

I fail to reproduce this issue. What is your dovecot version?

Do you got nested mailboxes? If yes, how many levels?

It would be easier to investigate with a full stacktrace...

Hi Alberto, I finally found the origin of this issue! Modoboa has a bad support for mailboxes hierarchy separator :p
