Yes, we never cared for that because we weren't aware of this leading
slash thing. (I wasn't at least, and never heard about it before.) So
we have to check all internals for problems.

There will probably also be problems with the toolkit.

The filename is used in several parts of the application. I expect
some of them to make false assumptions about leading slashes.

These are the things we have to think about, yes.
