Hello,
the problem still exists in:
Version: 5.4.0.2
Build ID: 2b906d450a44f2bbe506dcd22c51b3fa11dc65fd
CPU threads: 4; OS: Mac OS X 10.12.6; UI render: default; 
Locale: fr-FR (fr_FR.UTF-8); Calc: group

Just for note, as I am adding support to wb1's files in libwps(DLP) and the
encryption seems similar, this file contains a password structure: the zone 4b
of size 20:
- the first two bytes are a checksum of the password (which computed with the
first part of libwps::encodeLotusPassword),
- the 3rd and 4st bytes seems to be the password length(to be verified),
- the last 16 bytes can be used to decrypt the files with
QuattroParser::decodeStream.
