[Marcus Lundblad]

Package: gstreamer0.10-tools
Version: 0.10.23-2
Severity: normal

Pressing the "Test" button for the video input in gstreamer-properties shows a
still image.
The plugin is set to "Video for Linux 2" and "Device" to "Standard".
The input device in question is a Logitech Quickcam Zoom 4000.
When starting gstreamer-properties from a terminal, the following is output
immediatly when launching:

gstreamer-properties-Message: Skipping unavailable plugin 'artsdsink'
gstreamer-properties-Message: Skipping unavailable plugin 'pulsesink'
gstreamer-properties-Message: Skipping unavailable plugin 'glimagesink'
gstreamer-properties-Message: Skipping unavailable plugin 'sdlvideosink'
gstreamer-properties-Message: Skipping unavailable plugin 'v4lmjpegsrc'
gstreamer-properties-Message: Skipping unavailable plugin 'qcamsrc'
gstreamer-properties-Message: Skipping unavailable plugin 'esdmon'
gstreamer-properties-Message: Skipping unavailable plugin 'pulsesrc'

Then when running the test, the following message is printed repeatadly:

(gstreamer-properties:17825): GStreamer-CRITICAL **: gst_util_uint64_scale_int: assertion `denom > 0' failed

The webcam works in other applications like camorama and ekiga
