Backslash in strings works as escaping character, so if you want to have
a string containing only backslash, you have to write "\\". In "\"
second quotes are escaped, so they become a part of string, not a string
terminator - that's why compiler is complaining about missing
terminator.

No need to use Glib::ustring here - in gtkmm std::string is used for
paths. Also put it into a while loop, because there can be more than one
space.
