cacaxine totally broken in terminals

cacaxine works fine when it opens its own window, but is totally broken if it's asked to run inside a terminal.

To reproduce, execute:
$ unset DISPLAY
$ cacaxine any_movie_file

Expected: should work in the terminal just as when it does in its own window if you don't unset the DISPLAY.

Actual: Works for about a second, then the screen contents start falling apart. Tons of string that look like ANSI escape sequences (like "38;5;8" or similar) are printed on the screen. It even might cause the terminal to resize, move or iconify itself (it accidentally emits such escape sequences).

Usually, cacaxine segfaults a bit later.

Reproducible under any terminal emulator. (Note, however, that the incorrect sequences it prints might cause gnome-terminal to segfault: https://bugzilla.gnome.org/show_bug.cgi?id=647466)

Running under "script" and looking at the typescript file reveals it prints tons of "\e[\e[40m.34m" or similar sequences which is obviously incorrect. Apparently two escape sequences interleave each other. (Maybe it uses multiple threads without proper locking? Maybe xine is a multithreaded app and libcaca is not prepared for this?)
