Personalized animation crashes Moe

[tmtfx]

Taking a gif on the net, splitting it into its frames with gifsicle (gifsicle -e filename) (btw 3rd and 5th frames were not readable by the translation I had to convert them to pngs), then using Moe to generate animation (Moe --add-anime=anime --wait=100 files[0..23]) creates the attribute placed on the first file of the sequence.
But if I use it with Moe, the first frame appears then Moe crashes after 1 second.

Workaround: Use --add-anime=wink, as written in the docs, not --add-anime=anime.

Maybe there were plans to have different types of animations, but that seems the only working one now. I haven't gone deep in the code to know when each event happens, but MoeMascotManager sets up winking when there are any MOE:ANIME attributes and MoeMascot::Wink gets a list of bitmaps whose name start with WINK and chooses one of them without checking if there are any. When there are not, it plays a NULL one and crashes.
