.dot files sometimes rejected by writer

because CWW8 appears twice, once for normal .doc and once for .dot. So a .dot
files is tested twice if it's supported by the WW8 filter. Depending on the
(effectively arbitrary) order they appear in the list .dots may fail the "is a
normal non template .doc" test after the "is a template .dot" test and get
rejected as a CWW8 candidate.
