Comment 82 for bug 55567

I can confirm this bug on Ubuntu 11.10 and 11.04 - cheese starts, but doesn't show any picture from webcam :(

~ $ uname -a
Linux ubuntu 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux

~ $ lsusb |grep 0402

  ~ $ dmesg |grep m5602

Sometimes cheese shows this error in terminal: libv4l2: error dequeuing buf: Input/output error

~ $ cheese
(cheese:7182): Gtk-WARNING **: Attempting to add a widget with type GtkImage to a GtkButton, but as a GtkBin subclass a GtkButton can only contain one widget at a time; it already contains a widget of type GtkLabel
