There is no proof yet that it is a problem with usp10 (changing component back
to unknown).
I can reproduce the crash on my system (Fedora 17 32 bit) and with a clean
wineprefix.
When you select Latin + Latin Supplement charset, there are 2 character slots
which appear empty in the application. One is at position 32 (that should be
<space>?), the other one is at position 160.
When you select any of those two characters and click on <Visualize> or <Save
bitmap font as...> in options, the application crashes with a divide by zero
error. Selecting any other characters doesn't result in a crash.

Neither corefonts nor native usp10 help.
A +relay,+font,+seh,+tid debug log would be probably helpful for those who are
good at reading such logs.
I can confirm the bug btw.
