xdg-open issue

Hi all! I just came around an anoying xdg issue: $ xdg-open justapdf.pdf This opens a pdf, but with Gimp! I fiddeled around with gimp.desktop without success. I fiddeled around with xdg-mime without success: $ xdg-mime query default application/pdf /opt/trinity/share/applications/kde/kpdf.desktop but it opens gimp. IMO xdg-* is quite broken. :-( Now the only workaround I came up with is setting the environment variabe DE to kde: export DE=kde Then xdg-open uses kfmclient and that calles the kpdf. Now, would it be possibel to let TDE set that variable by default or am I missing a vital point? Nik
