Qt lgpl problem

Hi all.
I know this might be a stupid question. I'm trying to release my software with Qt using lgpl.
The problem is I don't know how to choose the license for Qt (QMessageBox::aboutQt() says that my software is using Qt open source and that I can't use it for closed source Software). Am I missing something or was Qt suppose to let me choose lgpl on installation?
Thanks.

it's a bug in dialog. Trolls forgot to change it. :)

Thanks. Now that is a nasty bug :p. Does someone know if it was posted as a bug for QtSoftware to fix :cool:

I don't know exactly, but one guy from Qt Software told about this bug.
yes, there is a bug report on bug-tracker.

this is it
