QThread locks process on folder

cronicryo

i'm trying to convert qt's QFileInfoGatherer to python the code below is a stripped version of it. The issue im running into is that when QFileSystemWatcher is inside of the Thread it locks the folder if a folder is in its children.

so lets say you have the folders:
path/A
path/A/B

you cant delete A from an os level because a process is latched on you can however delete A AFTER B is deleted.

How can i fix this? or what am I missing?

from PySide.QtCore import *
from PySide.QtGui import *

class FileGatherer(QThread):
    def __init__(self, parent=None):
        super(FileGatherer, self).__init__(parent)

        self.muteX = QMutex()
        self.condition = QWaitCondition()

        self.abort = False
        self.paths = []
        self.watcher = QFileSystemWatcher(self)

        self.start(self.LowPriority)
    def run(self):
        while True:
            locker = QMutexLocker(self.muteX)
            if self.abort:
                return
            if not len(self.paths):
                print "waiting"
                self.condition.wait(self.muteX)
            else:
                print "running"
            locker.unlock()
