Tag editing with opera not working

[Benjamin Mesing]

Hello,

when accessing the tag-editing page for a package [1], Opera shows only
the default page: 
        <HEADER>
        Package to edit: <InputField> <SearchButton>
        <FOOTER>

No error is reported in the error console :-(

Regards Ben
