segmentation-fault

Hi, All!

I have some Qt application with QPlainTextEdit in Tab widget. When try to make a pointer on it

QPlainTextEdit *w = (QPlainTextEdit*)ui->tabWidget->widget(0)

and call a document() method

w->document()

I get a segfault.

But if i call document directly, e.g. ui->mainEdit->document(), then everything works fine.

Can anybody explain me why it happens?
