This one is weird. Apparently some combinations of polyphony, manual beams, and a dotted rest followed by a note, trigger a "Wrong type" error (Windows XP here). Many variations I've tried still trigger the error, while other variations don't. You can experiment for yourself.
Unlike the stemlets-over-rests-only bug which I submitted yesterday, this one actually interferes with real-world usage. The complete error message in context is: "Preprocessing graphical objects...ERROR: Wrong type (expecting real number): #<unknown-type (0x27 . 0x13c9e48) @ 0x35bbb80>" Marcus % The following results in an "ERROR: Wrong type (expecting real number)" % even if the beamed rest is lengthened or shortened (as long as it's dotted) % even if the beamed note is lengthened or shortened % even if (certain) rests are inserted between, before, or after those two. % The manual beaming and the polyphony both appear to be necessary. \version "2.10.33" \paper{ ragged-right=##t } { << { r8.[ b16] } \\ % originally: r8[ r16. r32 r8 r16 r16 b8 r32 r16. r8] { r4 } >> } % originally: r4 r r r _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org http://lists.gnu.org/mailman/listinfo/bug-lilypond
