Segfaults with empty content folder

[vgmoose]

The game @CreeperMario and I maintain, Space Game, has no content folder as it's all OSScreen based and uses no external files. (The ELF has audio, but it hasn't implemented in the RPX yet, and all images are loaded as bitmap arrays as a carryover from browserhax)

When I first ran makefst, I created an empty "content" folder, as I thought it was required. This results in the following:

$ ./makefst -out space.woomy -icon space_game/meta/iconTex.tga -name "Space Game" -internal "space" space_game/
Compiling directory 'space_game' under TID 00050000505A4B00, Group Id 0x6D32, ver 0...
6 files, 10 entries total
Segmentation fault (core dumped)

Removing the empty content folder, or putting an empty file in that folder, allows the .woomy to be made successfully.
