Problem with repeating url parameter (Get variables)

Hi,

I secure only one page that contains a contact form. The addressee of the email is defined by a url parameter (Get variable), e.g. /?id=123.

When calling the page with http://domain.tld/email/?id=123 it switches properly to https but repeats the query string twice or even more often, e.g. : https//ssl-proxy.tld/domain.tld/email/?id=123?id=123. As the repeating string is always the same it does not cause any technical problem but it looks quite daft.

Any suggestions? (WP version 3.5.1, plugin version 3.3.0)

Regards
Mattki
