Cheese closes with segmentation fault

libv4l2: error dequeuing buf: Input/output error

libv4l and my webcam have crashed gstreamer-properties, cheese, and skype.

Gstreamer-properties crashes with this:

(gstreamer-properties:2972): GStreamer-CRITICAL **: Failed to deactivate pad v4l2src5:src, very bad.

Subsequent attempts to use the webcam show this:

gstreamer-properties-Message: Error running pipeline 'Video for Linux 2 (v4l2)': Cannot identify device '/dev/video0'. [v4l2_calls.c(493): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src1:
system error: No such file or directory]

And somehow, after some time, /dev/video1 is created, and if I selected it works, for a time. When *that* crashes, again, somehow, after some time, /dev/video0 exists again, and it "works".

On skype the video crash happened within the minute.

My HW: Aspire One 535h, Acer crystal eye webcam.
Ubuntu 11.04.

Status changed to 'Confirmed' because the bug affects multiple users.

this is what i recive - ubuntu 11.04, chickoney web cam (toshiba A205)

For me it fails in 11.10 as well

Ubuntu 12.04, when run from command line this is what I receive:

Segmentation fault

For an experiment, I tried running it without my external USB camera plugged in.

It successfully launched and stayed open with this message:

** (cheese:3192): WARNING **: cheese-window.vala:1624: Error: No device found

Otherwise with the camera plugged in I received the segmentation fault error.

I have the same problem to jaimina1
