in 0.61.2, this behaves differently:

Grouped Data: score ~ 1 | Worker
Error: attempt to type-coerce non-vector

In both cases, that is.

However, applying print.data.frame directly or indirectly by removing
the print method, on the structures gives a print of the data frame in
the 1st case and a segfault in the 2nd.

A quick tour into the debugger show that it dies trying to do
CHAR(x[i]) with x[0] == 1, -- and  x[1] == 2, etc. Methinks that
row.names<-as.character(1:54) might help! 

However, one should probably also do the explicit coercion of rownames
to character in  printDataFrame...

But where did the type-coerce error come from?
