Please note that \partial has been changed very recently in the 2.19 
versions. The documentation for 2.19.25, 
http://lilypond.org/doc/v2.19/Documentation/notation/displaying-rhythms#index-_005cpartial-1 
says that the duration specifies the remaining length of the current 
measure, which in my example is zero. Note also that my example works 
fine if I remove the R2*3 line directly below \time 3/4.
