Coverity complaints down from 1687 -> 1141, lots of easy ones in clear view to remove. They are not system threatening.

[martin kersten @martinkersten]

[martin kersten @martinkersten]

@matburst oops, your Python SQL ;) Which by the way is undergoing a major renovation cycle.

[martin kersten @martinkersten]

@Curtmonash twittering is a new concept...haha

[martin kersten @martinkersten]

@matburt Then the cause is hard to find. It may be a problem in either your JDBC (ODBC) application. We have seen that before with others

[martin kersten @martinkersten]

@matburt was not able to quickly localise your bug report, but will check the group tomorrow
