Download using FTPS makes wget abort

Description of problem:
When downloading a file over FTPS, wget aborts.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
# Modify the default vsftpd.conf
cat >> vsftpd.conf << EOF
openssl req -newkey rsa:2048 -nodes -keyout a.key -x509 -days 365 -out a.crt
echo test > test
systemctl restart vsftpd
It shouldn't abort, should exit in a regular way.
The following works:
wget --no-check-certificate ftps://localhost/pub/test
The SIGABRT occurs in the error-handling switch at src/ftp.c:1973. The getftp() call a few lines above it returns VERIFCERTERR because of the bad cert, but the switch doesn't handle that particular result and ends up abort()ing the process in the "default:" branch. If I append "case VERIFCERTERR:" to line 1975 (similarly to the way the situation is handled in src/http.c), no abnormal termination happens and wget exits with retcode 5.
Hopefully this saves someone a bit of debugging.
Referenced: vanilla wget-1.19.1, but everything is probably valid for 1.19.1-3.fc26 as well. The bug is also found in upstream git.
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
