このところ立て続けですが、ectoが 1.0.5.2にアップデートしていました。
Historyを見ますと...
• Several fixes to del.icio.us support, including the following two: It's now possible to submit a link using multiple tags. Also, description of a link is smartly determined from text or title of a link.
• Fixed a serious problem when servers return null fields for some blog entry data. These null fields would prevent ecto from storing data locally. This is now solved.
• Updated French and German localization.
• Fixed issue where localized strings would show up in IMG tag's align attribute.

Yamatoさん、ありがとうございました。
