Odd spacing in combination of reledmac and quoting

In the following example the last line of the quoting environment has an odd vertical spacing. I intend to use the quoting package mainly for the possibility of setting rightmargin=0cm.

documentclass{memoir}
usepackage[rightmargin=0cm,vskip=0cm,indentfirst=false]{quoting}
usepackage{lipsum}
usepackage{reledmac}
begin{document}
lipsum[1]
begin{ledgroup}
beginnumbering
pstart
begin{quoting}
lipsum[2]
end{quoting}
pend
endnumbering
end{ledgroup}
lipsum[3]
end{document}

Obviously, I would like to have the same vertical spacing between all the lines.
