Is this still an issue with the latest version of Wine?
I doubt it can ever be fixed. This might be a WONTFIX because this is an old version of Kindle for PC requiring an obsolete and unsecure certificate that was long removed from distribution. Nothing Wine can do anything about.
Though, it might be a good idea to document the workaround in the Wine AppDB for the affected Kindle for PC release (with the required certificate attached to the AppDB entry).
