Problems with gracenotes and metered music 2.5.19

[Herman Grootaers]

Ladies and Gentlemen,

I am currently busy with the encoding of our churchchoir's music in Lilypond 
2.5.19 on a mandriva 10.2 RC-2 machine.

I have a problem with two things:

1: The following lilypond-file and its output does not shape up to my 
expectations. If I remove all the recurring answers of the litany, it 
compiles correctly, but as soon as I add one or more of the recurring  
answers it fails to compile successfully. It gives the warning going back in 
time....

2: The bass/bariton will sometime sing in octave, but this I can not engrave 
it when the score says to use whole notes. Can you give me pointers jow I can 
solve this.

Greetings
Herman Grootaers
