Description of problem: From https://bugzilla.gnome.org/show_bug.cgi?id=711305 g_mime_object_write_to_stream() adds an extra space in the References: header after the colon. Version-Release number of selected component (if applicable): 2.4.19 How reproducible: Always when GmimeMessage object contains References: header Steps to Reproduce: 1. yum -v -y install epel-release 2. yum -v -y install make gcc gcc-c++ redhat-rpm-config git xapian-core-devel gmime-devel libtalloc-devel zlib-devel 3. git clone git://notmuchmail.org/git/notmuch 4. cd notmuch && make test Actual results: 37 tests fail since there is 2 spaces (one extra) after 'References:'. Expected results: Such diffs don't appear on output (some other, unrelated tests probably still fails) Additional info: In the repository git://git.gnome.org/gmime the commit cc96162a47bd88ba76cece5043a93b438e48c2c7 fixes this problem (first commit after 2.6.19 version tag).
Looking EPEL now (2018-05-30) the gmime package is updated to 2.6.23. So to me it looks like this issue is resolved. Just now I don't have a chance to test it, will do later...
Ok, tested, this particular case is not an issue anymore.
