setText in QTreeWidget Crashes?

[vishal.chauhan]

Hi All,

I am working on Qt 4.2.2 on my MAC.
I have set the text of the QTreeWidgetItem by using setText(QString).

I am getting the following crash report.

PID: 163
Thread: 0

Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000026
