help with ustring::erase

["Jamiil Abduqadir" <jalqadir gmail com>]

Hello everyone
Can someone tell me how to erase the first character in a string?
...
Glib::ustring str("Hola");
str.erase(1,0); // erase one character at position zero
std::cout << str << std::endl; // ola
with this code I get a run time error, can anybody help?

Thanks
