Package: libass4
Version: 0.9.13-1
Severity: grave
Tags: sid
Justification: renders package unusable

Hello,

Current libass version crashes freetype 2.4.6 when tries to render ASS
subtitles in mplayer or mplayer2. Here is backtrace (sorry, no dbg symbols
right now):
Program received signal SIGSEGV, Segmentation fault.

I'm not sure if those changes are included in current build.
