libxft2-dbg 2.1.12-3ubuntu1 (i386 binary) in ubuntu intrepid

 Xft provides a client-side font API for X applications, making the FreeType
 font rasterizer available to X clients. Fontconfig is used for font
 specification resolution. Where available, the RENDER extension handles
 glyph drawing; otherwise, the core X protocol is used.
 .
 This package provides an unstripped shared object with debugging symbols,
 useful to provide a backtrace with symbol names in a debugger; this
 facilitates interpretation of core dumps, and aids in finding logic errors in
 programs using this library (or the library itself). The library is
 installed in /usr/lib/debug and can be used by placing that directory in the
 LD_LIBRARY_PATH environment variable when the code to be debugged is
 executed. Non-programmers will likely have little use for this package, and
 should use libxft2 instead.
