It's not really a bug, as replacing ":||" with ":|" will
do what you want.  The LilyPond syntax defines "|:" ,
":|:" and ":|" as the notation for manually inserting
repeat-related barlines.  Then, because a start repeat
barline might need special processing if it occurs at the
end of a line, a special form of the notation is provided
to invoke this optional special processing - "||:".  No 
special processing is required for an end repeat barline, 
so ":||" is not required.  You might argue that there
should be two forms of the syntax for the end-repeat
barline, which behave identically, but the lack of that
feature is hardly a bug.
