Problems with Firefox 3.0.3

[minimost]

Hey Guys!

I'm having some problems with Roundcube 0.2beta.

When I try to delete a mail, the following error occurrs:



I took a look at the logs but they don't get any errors.

On Firefox 2.0.0.17 or IE 6 it works without any problems, but most of my people use Firefox 3.0.3, so i need to get this to work.

€: I'm running on FreeBSD 6.3 and Courier-IMAP v4.4.1 and qmail-smtpd-auth 0.31 & vpopmail 5.4.17
