Crash on secondary clicking in four preferences input fields

[jumase]

When trying to paste a URI into the "HTTP proxy" input field, Lagrange just crashes. The same issue happens on the other two Proxy fields and on the "UI scale factor". It is triggered by secondary-clicking on those 4 input fields. The others work as expected.

Running Lagrange from terminal, the error given in all of these cases is "Violación de segmento" in Spanish.

Can reproduce. Also seems to crash on Windows.
