[Qt-interest] qt creator can't evaluate expression when debugging?

[Li Li]

hi all,
    I am using qt creator to debug. I have a QUrl local variable. I want to
view it's value. But  Locals and Expressions view don't show anything. And I
add a line:   QString ss=qurl.toString(); the locals and expressions view
can display local variable ss. So I Insert NewWatch Item qurl.toString().
but it says <no such values>. I also tried QString::number(1). it can't even
evaluate this! What's wrong with it? I am using qt sdk 1.1.2 in ubuntu.
