system_update_7018() fails on sites using the Drupal 6 "jQuery Plugin Handler" module because {system}.type is too short

I run update.php on my D6 database. Everything seems to work fine UNTIL I try to access the converted site. Then I get the following error:

Checking a working D7 site, the table is definitely there. The other block tables, ..._block_custom, ..._block_role and ..._block are in the converted site some I'm not exactly clear what's going on here, but it looks like a bug to me.

Of course, I may have missed something.

Best,
