           Summary: incompatibility/inefficiency with
                    bitmap-fangsongti-fonts
           Product: Fedora
           Version: rawhide
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: unspecified
          Priority: unspecified
         Component: fontconfig

    Classification: Fedora


Description of problem:

bitmap-fangsongti-fonts causes fontconfig to exercise some very bad codepaths
on upgrades.

Version-Release number of selected component (if applicable):

fontconfig-2.8.0

How reproducible:

100%

Steps to Reproduce:
1. Have bitmap-fangsongti-fonts installed
2. Be running a desktop
3. Do some upgrade that causes '/usr/bin/fc-cache /usr/share/fonts/bitmap' to
run

Actual results:

Most every fontconfig app on the system (kde4d, notification area applets,
gnome-settings-daemon, and others) suddenly start using 100% cpu. The fc-cache
call takes a *very* long time to complete.

Expected results:

Not that.
