Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.

Admin note: I've deleted the PDF attachment that was previously in this bug, since as far as I can tell it's a breach of the author's copyright and thus not distributable by Launchpad.

[Eli Schwartz (eschwartz)]

FWIW standard policy is to mark such bugs as informationtype userdata (and the bug reporting guidelines for calibre ask reporters to do so), I guess some old bugs are still public though.

[Colin Watson (cjwatson)]

Thanks. In this case the direct librarian URL was quoted by a user in a public ticket elsewhere, so I wanted to get rid of it expeditiously. Though yes, now that I look at it, marking the bug as userdata would have been more or less enough - if this happens again then I'll do that.
