I've written a test case in Python to reproduce this bug. It could easily be
turned into a DEP 8 automatic package test.
The output looks like this:

You can see a gap in the list of mailboxes in the sidebar.
Here is the code. The python-pyte and python-pexpect packages need to be
installed.
import pyte
import pexpect
from random import seed, randint
from tempfile import NamedTemporaryFile
import os
def write_muttrc(f):
f.write('''
set folder=/tmp
set sidebar_visible
set sidebar_width=10
set pager_index_lines=4
mailboxes ''')
for i in range(30):
f.write(' =m{}'.format(i))
def write_mbox(f):
for line in ('From test@test Sat Oct 10 10:00:00 2015',
'Subject: test', 'To: test@test', 'From: test@test', ''):
print >> f, line
seed(1)
for i in range(25):
print >> f, ' '.join(chr(ord('a') + randint(0, 25)) * randint(1, 10)
for i in range(randint(5, 20)))
def run_mutt(muttrc, mbox):
stream = pyte.ByteStream()
screen = pyte.Screen(80, 24)
stream.attach(screen)
mutt = pexpect.spawn('/usr/bin/mutt-patched', ['-F', muttrc, '-f', mbox])
mutt.send('\n' * 5)
while True:
try:
buf = mutt.read_nonblocking(mutt.maxread, timeout=1)
except pexpect.TIMEOUT:
break
stream.feed(buf)
mutt.send('q')
return screen
def main():
f = NamedTemporaryFile(delete=False)
muttrc = f.name
write_muttrc(f)
f.close()
f = NamedTemporaryFile(delete=False)
mbox = f.name
write_mbox(f)
f.close()
for line in run_mutt(muttrc, mbox).display:
print line
os.remove(muttrc)
os.remove(mbox)
if __name__ == '__main__':
main()
