ebook-convert crashes on files with urlencoded characters in file name

[leastcommonancestor]

ebook-convert crashes on files with urlencoded characters in file name, e.g.

   ebook-convert Stirbt+die+Kunst%EF%BC%9F.html out.epub -v

Result is:

KeyError: u'Stirbt_die_Kunst%ef%bc%9f.html'

The error apparently does not depend on the file contents.
The error was already present in version 2.58.
