Sometimes the plugin choke when the it parses a bogus date and feed it to gramps.
That result in an unhandled exception, that gramps will popup.
Once we close the exception popup, the current person import dialog is still here but the plugin doesn't make any progress.
It doesn't continue, it doesn't try to go to next person, it's just stuck
See attached text for the full exception backtrace :
BUG.gramps-vs-genenaet.txt
(The first line was added by me to remember the person it was trying to import at the time.)
