[kdenlive] kdenlive 16.04 color clip/image clip surprises

[Karl Kiniger]

Hi again,

in current 16.04 try the following:

* new project (I chose 1080p50)

* add color clip - duration is shown as 5 seconds in project tree)

* drag and drop color clip to some video track - length in timeline is  5
  seconds - OK

* stretch or shrink the duration of the clip in timeline, e.g stretch it
  to 10 seconds

* project tree says clip lenght is still 5 seconds - OK

* again drag the color clip from project tree  to another position in timeline

* length in timeline is 10 seconds instead of 5 seconds  .... grrr

----------------

* try to add a PNG file as a clip - "all supported files" doesn't seem to
  include PNG, so choose "All Files"

* duration shows as 00:05:00:00 in project tree (is it really supposed to be 5 minutes??)

* however PNG clip is not affected like the color clip by changing duration

All the best,
Karl
