:sanitize broken for some items

[dkasak]

I'm unable to sanitize downloads, formdata and passwords using :sanitize. Vimperator reports Cannot sanitize <item> for each of the items mentioned. I've tested this with the latest master, with a clean profile and vimperatorrc and with no other extensions installed. I've confirmed that it really doesn't sanitize the items in question, so it's not just a spurious error message.

same here (formdata) cannot sanitize formdata

[Doubanma]

same here (formdata) cannot sanitize formdata, display TypeError: searchBar.textbox.editor is null

[dkasak]

:sanitize history now prints

TypeError: sanitizer.canClearItem is not a function

in the latest AMO version.

EDIT: Actually, it seems to print this for any item.

:sanitize <item> prints TypeError: sanitizer.canClearItem is not a function for any item and any choise for -timepan. On the other hand :sanitize! -timespan 0 reports no error but doesn't delete anything.
