lilypond crash with wrong \partial argument

[jmk]

if you uncomment the last line in the example below, lilypond crashes. 
windows then ask me if i want to send ... etc.

this is, according to windows, where the error happens:
--------
AppName: lilypond-windows.exe
AppVer: 2.9.7.1
ModName: lilypond-windows.exe
ModVer: 2.9.7.1
Offset: 00227a1a
--------

(btw. why does it still say that i'd have v2.9.7.1? i installed v2.9.10 
as soon as it came out...)


now, i know that there is the \partial "typo", but normally lilypond 
just gives me the normal error "error: not a duration: 3"

hope i could help,
jmk

example
-------------
\version "2.9.10"
\relative c'' {
\time 3/4
\clef treble
\partial 3*8 r8 r8 d,8
%g4 a8 b16[ d] c8 b
}
