calibre 2.71: Tools -> Arrange into folders fails

[DrChiper]

Since upgrading to 2.71, when trying to arrange an e-book (EPUB) into folders, every book I tried fails with:

calibre, version 2.71.0
ERROR: Unhandled exception: <b>WindowsError</b>:[Error 3] The system cannot find the path specified: u'C:\\Users\\<user>\\AppData\\Local\\Temp\\calibre_1ru_p3\\dkiiav\\00001-pwc299\\OEBPS\\*.*'

Any ideas?

Can you attach one of these books.

[DrChiper]

Sure. I found that books which have already some folder mapping do not fail but convert properly, or otherwise a message appears to indicate the file is already mapped. All others fail on me at the moment. See the other attachment for my settings which I always use (no recent change).

When I inspect the temp folder,
C:\\Users\\<user>\\AppData\\Local\\Temp\\calibre_1 ru_p3
there are no sub-folders there, just a couple of ipc_result_1_1_ujxjg7.pickle files which are empty.

Hope this helps.

Edit: Trying the same attached book with calibre 2.68 on another machine succeeds, so the epub is genuine.

Thanks Kovid.
Reinstalling 2.70 for the moment I guess. A pity, I just got used to the new icons ...
