qtranslate breaks post archive

Hi all,

Since a long time I have issues with the post archive (via categories or date) in my blog. Although, for example, for Dec 2009 there are 25 entries, I don’t get one single entry shown when clicking on the respective archive page (for example here ). However, this doensn’t happen with every archive page, but only some (see p.ex. here for a working archive page ).

All these problems disappear when deactivating qtranslate.

Did anybody encounter this problem already?
Thank you for your help
Philipp
