Thanks for the report.  (please direct it at bug-lilypond, however)

Would it be possible to construct a smaller example that demonstrates this problem? I don't think you need any special \layout{ context{} } things to produce this bug, and it would make it much more clear what was happening.

Cheers,

I get the following errors when running lilypond against it:
$ lilypond ./test.ly
GNU LilyPond 2.10.0
Processing `./test.ly'
Parsing...

programming error: no heads for arpeggio found?
continuing, cross fingers
Layout output to `test.ps'...
Converting to `test.pdf'...


The resulting ps and pdf files look ok, but yet lilypond outputs the errors.  If
I use:
upper = \relative c'' {
...
  <a, b fis'>2\arpeggio <b g'>4 |
...

lower = \relative c {
...
  <a d>2.\arpeggio |
...
}

Then the 'no heads for arpeggio found' error goes away (lilypond seems to want
to have at least two notes on each staff for the arpeggio, even though I have
\set PianoStaff.connectArpeggios = ##t).

2.8.7 displays the same two errors, but 2.6.3 (from ubuntu Dapper) does not.

Please CC me as I am not on the list.
