No problem - all I personally ask for is intelligent conversation :-)

Does sound like some kind of corruption.  The short term solution is to 
simply delete the OpenSim.db table which is where OpenSim stores all its 
region data.  OpenSim will automatically recreate it on startup.

If it happens again, please could you capture the original exception 
when you tried to store the prim and Mantis 
(http://opensimulator.org/mantis) it?  This will help us track down what 
the issue is.

I think this list is fine, though for failure cases such as this you 
might want to go to opensim-dev (or alternatively, post a bug on Mantis).
