I've tried to play this:
./vlc --sout 
--freetype-rel-fontsize 18 --freetype-font 
/usr/share/fonts/Courier_New_Bold.ttf --subsdec-encoding ISO-8859-2 

but after a short while it segfaulted... :)

here's gdb's backtrace:

Program received signal SIGSEGV, Segmentation fault.

any ideas?

I've tried to make a patch, but I've also failed :-)
