Python imgmsg_to_cv2 memory leak

[cburbridge]

When using the imgmsg_to_cv2 function from Python cv_bridge.CvBridge class, memory is leaked if colour conversion is performed. I am using the latest Hydro release, code like this:

    def image_cb(self, image):
            try:
                ## This leaks, using colour conversion:
                #self._image = self.bridge.imgmsg_to_cv2(image, "bgr8")
                ## This works, no conversions:
                self._image = self.bridge.imgmsg_to_cv2(image)
            except CvBridgeError, e:
                print e

Looking at the refcounts for self._image.block, they are screwed up when using colour conversion and fine otherwise. Am I just missing something?

Yep, fixed, and incredibly fast :-) Thanks.

cool ! Releasing for all releases then. Memory leaks need to be fixed fast :)
