exactly - probably good to open a ticket, if not already

copy-paste, as you noted, is fragile, and I would not particularly
encourage its use. Save as... however should work.

AFAIK it's a GDAL issue - perhaps you could check if ogr2ogr works for
you, and open the ticket where appropriate? (gdal or qgis)

This is a long standing problem. I'm gradually trying to convince new
plugin authors to add a code repo and a bugtracker; for older plugins,
we have to ask. Perhaps a direct email to the author could help.

All the best, and thanks for raising the issue.
