QSystemStorageInfo::availableDiskSpace() crashes with KERN-EXEC 0 panic

Hi,

We are instantiating QSystemStorageInfo class in the main thread and in the secondary thread of our application in order to retrieve "availableDiskSpace()" information. We observed that this call is working properly in the main thread but crashing with KERN-EXEC 0 panic in secondary thread. Call Stack for this panic is given below:

If i won't call this from main thread, but calling in two QThread instances, then in the first instance of QThread, this call succeeds, but crashes in the second instance of QThread. I am attaching a reproducable sample application (QSystemStorageInfoTest.zip attached) to support this problem. Call Stack for this panic is given below:
