yes, that's usually what i do, my error (i pushed the wrong button, i
need more cafe), sorry

I found  ..my bug....

Gtk::Image(filename) takes an std::string instead of char* as the
previous function i used did

so i converted some variables from char* to std::strings

and some variables where initialized to NULL (no icons), which leads to
a std::logic error

i corrected to initialize the variables to an empty string, and
everything is fine.

Thank you for your valuable help

P.L.
