 > As far as I know, `g.gui.iclass` is not using `i.gensig`. There is a
 custom mechanism of creating the signature files taken from `i.class`.

 was moved the the library. It is not really good but it was the fastest
 way to implement it without need of a new module, format or change in
 functionality comparing to `i.class`. See also

 I don't have the time to dive into the code, now, but is there no
 message/error handling in the i.class code concerning the signature
 creation (and notably the "Signature X not invertible" message) ?
