CSV Import: Error when combining escaped commas and multiple values

With the latest version of CSV Import (2.0.3) I've encountered the following problem, using tilda as the delimiter for multiple values for an element.

This works -

TITLE,ABSTRACT,YEAR,AUTHOR,VOLUME NUMBER,PAPER NUMBER,PAGES
JOINT MEETING WITH ROYAL INSTITUTION OF NAVAL ARCHITECTS Independent Safety Assurance,Sample abstract text.,2004,Rudgeley Gavin~Marshall Steve,147,1606,5-16

This works -

TITLE,ABSTRACT,YEAR,AUTHOR,VOLUME NUMBER,PAPER NUMBER,PAGES
JOINT MEETING WITH ROYAL INSTITUTION OF NAVAL ARCHITECTS Independent Safety Assurance,Sample abstract text.,2004,"Rudgeley, Gavin",147,1606,5-16

This doesn't work -

TITLE,ABSTRACT,YEAR,AUTHOR,VOLUME NUMBER,PAPER NUMBER,PAGES
JOINT MEETING WITH ROYAL INSTITUTION OF NAVAL ARCHITECTS Independent Safety Assurance,Sample abstract text.,2004,"Rudgeley, Gavin~Marshall, Steve",147,1606,5-16

The item doesn't appear in the database in the final example.

Try turning on error messages and logging, and see what appears in the error log

It looks like CSV Importer is getting confused by the combination of quotation marks, which gets you around the problem of internal commas, and the tilde you are using as a different separator. Hopefully something in the logs will help nail that down.
