calibredb update bug with 0.7.21?

[_Em]

I just upgraded to 0.7.21, and discovered that calibre_guess_and_add_isbn is suddenly broken. Error below:

Python function terminated unexpectedly: write_dirtied() takes exactly 1 argument (0 given)
Traceback (most recent call last):

This didn't happen with 0.7.20; I've verified that the command line tools are properly symlinked.

It appears that the opf file gets correctly generated by the script, but then calibredb set_metadata fails on update.

When running it by hand, I get:

However, adding the data manually through the gui edit window works perfectly????

{edit:} rolled back to 0.7.20 and everything works. So I'm using 0.7.20 for cmdline and 21 for gui

Typo, fixed in next release.
