Hi
The reason that I reassigned it to that package is that I can not see
how lightspeed can distroy the internal data structure in fontconfig
so that it on finalize of the structure makes an assert. The lightspeed
application do not even call this function.
I think it is valid to forward this bug. But maybe I did not give enough
proof on that the problem is in fontconfig.
I can see a number of reasons why this has been introduced (changelog in
reverse order):

As you can see lightspeed uses gtk directly and according to the source that
I can not find any place where lightspeed itself can trigger this case, unless
it is a bug in some other place.
