Trash inbox not empty but not showing any messages on rel0.1 beta2

[DylanDog]

Hello
I use Roudcubemail Version 0.1-beta2.
I run it on a shared web server (Apache/2.0.54 (Debian GNU/Linux) PHP/5.2.3 with Suhosin-Patch DAV/2)

It was stable until few days ago then suddenly it happened that the numbers of email in the trash folder is showed on the left bar but when selecting it I cannot see any email...I cannot therefore clean the Trash folder or view deleted emails.

Can you please help?

thanks!
