Comment 1 Juergen Rose 2015-12-22 18:53:30 UTC 
g-octave is currently not installed. Nevertheless there is /var/lib/g-octave tree. Can I delete this tree?
Comment 2 Juergen Rose 2015-12-22 19:08:15 UTC 
The deletion of the empty directory /var/lib/g-octave/eclass was enough to enable the installation eclass-manpages-20150814-r1.
Comment 3 SpanKY gentoo-dev 2015-12-23 01:11:26 UTC 
eclass-manpages walks the repos you have registered.  if you have that one registered, and you have an eclass dir in there, then the package expects you to have files in there.
Comment 4 Martin von Gagern 2016-01-04 13:59:51 UTC 
Any harm in "shopt -s nullglob" to avoid this problem?
Comment 5 Georgy Yakovlev archtester gentoo-dev 2018-05-05 08:12:16 UTC 
still happening.
had a repo with empty eclass dir and it failed.

Comment 6 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2019-03-27 17:21:55 UTC 
We no longer handle custom repos, so this should be gone now.
