How to avoid the presence of new line in GtkEntry at the end of input string

[arkkimede <arkkimede gmail com>]

Hi!
In my GTK3 applications, there are some GtkEntry used to input strings
like, e.g., the output directory.

I write a string in the Entry and using the function gtk_entry_get_text() i
read the string insert in the GUI.

Printing on screen this string, <<some times>> a "new line"  is present at
the end of the string (obviously I do not put a new line at the end).

How can avoid this issue?
I have to change function or make some operations before the reading?

Thank You.
