[Qgis-developer] Bug with Models in Processing?

[matteo]

Hi guys..

I built qgis master2 (ubuntu xenial) and I noticed that it is not
possible to save models of Processing.

When I try to save the model the dialog of the file manager appears but
it freezes and nothing happens.

With old models already saved I can edit them and correctly save them,
so it happens just with new models.

Somebody confirms this issue or is just a problem of my computer?

Thanks

Matteo
