Hi!

I have roundcube 0.8.4, with lang_sel plugin enabled.
When i change the lang, and after that i login, a get a

SERVICE CURRENTLY NOT AVAILABLE!
Error No. [524]

The URL is: https://###/roundcube/?_task=mail&_lang_sel=en_GB&_action=plugin.lang_sel

If i click on the Mail or Settings, i can use roundcube without error, with the selected language.
Or if i delete the _action part of the url, everything is all right.

What's wrong?

Thanks for your answers!
