I think the idea is, certain fonts in his collection may be corrupt,
and he wants to just scan through and load them, ignoring the ones
that make the program crash. The bug in this case lies with a third
party and isn't something he can easily fix (although he can file
reports to the third party (PIL)).
This has come up for me as well with loading meshes in a 3d
application. The user or someone may include a corrupt file, and it's
not nice for the application to just crash when that happens, asking
them if they want to debug it. I haven't really found a solution,
just have tried to prevent corrupted files in the system for now. Let
me know if you get this solved :)
