3.3RC2, observed on gtk-64, likely happens on all platforms

- create an Update Site project, which auto-opens an editor
- create two new Categories
- select one of the categories, right-click -> Cut
- select the other category, right-click -> Paste
- the trace below is written to the error log:

Resolving as DUP of Bug # 189472.  Generalized that bug report to indicate clipboard operations are broken on the whole for the "Site Map" tree viewer.

Need to discuss with the rest of the PDE team as to whether this is serious enough to tackle for 3.3.
