Bug#1029752: tests fail with nmh 1.8~RC-2, blocking nmh from entering testing

[Alexander Zangerl]

Package: xlbiff
Version: 4.6.3-1
Severity: important

xlbiff's autopkgtests fail (silently) with nmh 1.8, which means that
version of nmh cannot enter testing. the autopkgtest
"regression" log files are devoid of any useful information, so i
cannot pinpoint *what* in xlbiff fails, but something is broken.
