Corrections.
After a clean install of rev with no plugins, the code works as long as 
the referenced imagepixmap exists in memory.
This means one can reference hidden stacks. Otherwise no error is 
thrown and rev crashes.
In metacard the code works only  if the own pixMapID is referenced. 
Referencing other stacks crashes metacard irrevocably.

Sorry for the fuzz,
