This was an internal bug in do_title.  When the integer vector was 
converted to character it wasn't protected, and garbage collection in 
the middle of drawing it threw it away.  I suppose it could happen with 
any title that needed conversion, but the large size of this one made it 
more likely that GC would happen.  Soon to be fixed in R-devel and
R-patched.

Thanks for the report.
