Public bug reported:
This issue occurs upon boot and when attempting to open the Unity video
lens.
The process: python /usr/lib/unity-lens-video/unity-lens-video uses all
available disk IO causing full system performance decrease and
application hangs (grey outs). 98-99% IO while monitoring with IOTOP.
This happens for about 5 minutes on boot without clicking on the lens
and once that has completed it starts to happen again when you click on
the lens. The lens does not even work during this long process.
This is most likely exasperated by the widely experienced kernel disk IO
and scheduling bug which has been ongoing for some time now. Some
improvements have been made but I'm not sure if they have all been
imported into the latest stable Precise kernels.
I suggest that the video lens should not be installed by default as
normal users will not understand why their PC is freezing for no reason.
Can anyone else confirm this issue or is it specific to my PC and amount
of files.
Takes about 5-10 minutes for the system to become usable again. Then the
Video lens once again provides search results.
