I haven't really looked into this in detail but my guess is this is
the Linux v4l2convert.so that is LD_PRELOAD'ed into skype for the
benefit of cameras not able to provida yuv video.  So I guess we'd
need to prepend a wrapper for xdg-open to PATH that resets LD_PRELOAD
before executing the real /usr/local/bin/xdg-open .  (And btw I had
to do something similar for google earth which sets LD_LIBRARY_PATH,
see

	/usr/ports/astro/google-earth/files/browserwrapper

and

	/usr/ports/astro/google-earth/files/patch-bin-googleearth

.)

 Hm or should the xdg-utils port be patched to just unset LD_PRELOAD
uncondtionally?  I'll Cc gnome@ which is listed as maintainer for
that port...

 Cheers,
