Unknown Sources Problem

[Saurabh Sood]

Hi,
I had made a dataengine, which was working. Then, I changed some code,
and since then, it has not worked. I tried commenting most of the
functions that could have caused the code not to work, but to no
avail. I keep on getting 'Unknown Sources' in plasmaengineexplorer.
Also, in the konsole, I get 'Unversioned Plugin'. Please guide me on
correcting this problem. The link to my project is at:
