[Pkg-fonts-devel] issue with pango 1.20, ttf-sil-charis, ttf-sil-abyssinica, pango-graphite

[Paul Wise]

Hi all,

When pango was upgraded to 1.20.0 in sid I experienced several text
rendering issues; some digits/letters looking different to others, huge
spacing between lines in evolution and liferea, totally messed up
rendering in xchat and others. Installing pango 1.18.4 fixed the issue.
After a while packages started depending on >= 1.20.0 so I purged lots
of fonts which got rid of this issue. I finally had time to track down
which fonts caused it. I tracked this down by purging all fonts from my
system one at a time. When I removed both ttf-sil-abyssinica
and ttf-sil-charis the issues disappeared. When I installed either one
on its own, the issues returned but in slightly different form. It
appears that ttf-sil-charis overrides ttf-sil-abyssinica which
overrides dejavu. Here are some screenshots of the issues with xchat,
pango 1.20.1 and with & without the problematic fonts:

I have the latest versions of  libgraphite3 and pango-graphite from sid.
When I purge pango-graphite the font issues are no longer there.

So, I imagine that the problem is that pango-graphite is incompatible
with pango 1.20. Does anyone else think that this is the correct
analysis? Is there a new upstream of pango-graphite that works with
pango 1.20 or is one planned? Perhaps the pango modver should have been
bumped? Any other thoughts? I didn't file any bugs yet because I wasn't
sure which package(s) are at fault.
