[XeTeX] Trouble with the new Xetex

[Andrew Gollan]

I am using the Palatino Linotype font which does not have a native ȳ glyph.

I had been entering my ȳ letters as \=y which was working fine until I
upgraded to TeXLive2011 (from 2009/2010 depending on machine). Now I get the
error message:

 ** ERROR ** Invalid glyph index (gid 1329)

Output file removed.

I have attached the .log file. Which contains the following line for each ȳ.

Missing character: There is no ȳ in font Palatino
Linotype/ICU:script=latn;lan
guage=DFLT;!

Any clues as to why this appears to have gone backwards?
