Hello

Recently, I have had trouble using git send-email to send a patchset.
After the confirmation to send the email I get the following:
Send this email? ([y]es|[n]o|[q]uit|[a]ll): y
[Net::SMTP::SSL] Connection closed at /usr/lib/git-core/git-send-email
line 1320.
fatal: 'send-email' appears to be a git command, but we were not
able to execute it. Maybe git-send-email is broken?

This message first appeared when I tried to send a 19 commit patchset
via 'git send-email HEAD~19'. It also fails when I try to format-patch
and send the patchset separately via 'git send-email 0001...'
Oddly enough, it works when I send anything other than 19 commits
for example 'git send-email HEAD~1' or 'git send-email HEAD~20'

I thought it was something with the gmail servers but I was able to send
the patchset by downgrading a couple perl packages
warning: downgrading package perl (5.22.0-1 => 5.20.2-1)
warning: downgrading package perl-net-ssleay (1.68-2 => 1.67-1)

Note perl-net-ssleay depends on perl 5.22 so I can't isolate which
package but I can consistently get the failure with the newest packges
and it works fine with the downgraded packages.

Running Arch Linux
git 2.4.5
perl 5.22.0
perl-authen-sasl 2.16
perl-mime-tools 5.505
perl-net-smtp-ssl 1.03

.gitconfig
[sendemail]
    smtpEncryption = tls
    smtpServer = smtp.gmail.com
    smtpUser = juston.h.li@gmail.com
    smtpServerPort = 587

Regards
Juston
