Generally this mean pango was not configured with the cairo backend.
DirectFB requires the cairo backend in pango.

If you know how to check this in autoconf I should add a check.

I remember the debian-installer guys having this problem too.  No idea how they solved it.  Lets see if we get more info.
Comment 3 Michael Emmel 2007-09-14 22:15:13 UTC 
Yep saw that thread.

My opinion is distros should start supporting DirectFB and we just compile everything for both. Only Cairo is a pain because it does not load its backends from libraries. Otherwise its basically transparent. I think the decision to link in the cairo backends is a mistake. The glitz backend should be used if you have a good 3D driver for example if your local IMHO. This is not a compile time decision. But bitching about cairo design decisions in a gtk bug is probably a waste of time :)

Well, you definitely know where to nag about cairo!

Hi,

 With the patch for cairo(cairo_show_glyphs.patch) given in gtk-devel-list@gnome.org by Denis Oliver Kropp, this probelem is solved. I checked it with cairo-1.2.6 and gtk+-2.10.14.

Thanks & Regards

The issue was in cairo-dfb backend. This fix is already in cairo source tree and is expected to be in from cairo version 1.5.5 onwards
