[MPlayer-users] Another Segmentation Fault

Hello, I am converting videos uploaded via a web form, when I changed
servers it created some issues most of which I resolved... except video
uploading is proving difficult.
I have tracked it down to mencoder. Which gives a segmenation fault, and
thus does not create the required FLV file. It perhaps is something to do
with fonts I am unsure. Here is what gdb has:
