Bug#898893: fontconfig-config ≥ 2.11.? should Breaks: 2.13.0-5

[Jonathan Dowland]

Package: fontconfig-config
Version: 2.13.0-5
Severity: normal

It's possible to satisfy stable's fontconfig dependency on fontconfig-config with sid's
version, although the config files appear to be completely incompatible. I think
fontconfig-config is lacking an appropriate Breaks: header for the versions either
side of the config file language change.

The consequences are a lot of fontconfig errors on stderr, and very unreadable
fonts :-)

(I ended up in this situation by upgrading fontconfig* to sid by installing sid's
"firefox", then later downgrading to install stable's "wine".)
