mplayer-devel hangs with white screen

[jchauvel@…]

Summary of the bug:

When a video is played it shows a white screen and plays the first fraction of a second of the video's audio and then hangs.

I've installed mplayer on OS X (Mavericks) via macport's mplayer-devel package. The package is installed with the following variants:

mplayer-devel @36449_4+a52+aa+caca+dirac+dts+esd+fribidi+live+mencoder_extras+mng+noappleremote+nodvd+osd+sdl+smb+speex+x11

Just for the record: That's usually caused by font loading. Attach to the process with opensnoop (e.g. using the -n flag) to see some progress while it does that.
