404 when trying to use Export feature with a non-english language

[augusto]

We have just updated Zimbra OS to 5.0.13_GA_2791.RHEL5_64 (previously we were using 5.0.9) and the new Import/Export feature comes up. This is a wonderful new feature and our thousands of users are very interested in it.

The problem is that no folder under (and including) Inbox, Chats, Sent or Junk is being exported probably due to an incorrect URL. When we change language to English everything works fine, but when using Portuguese, the button "Export" does nothing. Analyzing the HTTP request, the URL for Portuguese interface and English interface differs as follow:

English Interface:

http://<host>/home/<user>/Inbox?fmt=tgz&filename=Inbox-2009-02-16-092752

Portuguese Interface:

http://<host>/home/<user>/Entrada?fmt=tgz&filename=Entrada-2009-02-16-092408

The second URL returns a 404. Maybe Zimbra is erroneously translating "Inbox" to "Entrada". That's what I guess but I am not sure.

Is there any workaround for that?

Thank you!
