Yes, there have.

Yes, it is.

The xetex.def that is included with xetex has been updated so that (I  
believe) it works correctly.

Stephen, I notice you have a local copy (./xetex.def); that's why  
you're seeing this problem. Try removing it, so that the latest  
xetex.def from the distribution is used instead.

The issue is that a "quoted filename" (for \input, \openin,  
\XeTeXpicfile, etc) is no longer necessarily terminated at the  
closing quote; you need a space (or \relax, I guess) to terminate it,  
just as if it were an unquoted name. This can be a little surprising  
sometimes, but matches the behavior of pdftex, and is necessary when  
macro packages want to take a quoted name (e.g., \jobname with a  
space in it) and append extensions (like .toc, .aux, etc).

xetex.def previously had lines such as:

    \edef\picfileargs{ \XeTeXquote#1\XeTeXquote\picpage}%

which used to be OK, because the quotes around #1 ensured it was  
terminated at the "expected" place; but this now needs to be changed to:

    \edef\picfileargs{ \XeTeXquote#1\XeTeXquote\space\picpage}%

As mentioned, the latest shipping xetex.def includes these updates  
(which is why the test file worked fine for Akira).
