The difference between my testcase and yours is the blank space after the single quote.
Try your testcase with
style="background-image: url('http://www.example.com/icons/apache_pb2.gif');"
instead of
style="background-image: url('http://www.example.com/icons/apache_pb2.gif' );"
and you'll see that it works.
The W3C CSS validator will not report an error for such blank space nor will the WDG CSSCheck service. So, it looks like you have a valid bug here.
DOM inspector reports
style="background-image: url( );" for the body element.

The format of a URI value is 'url(' followed by optional whitespace followed by an optional single quote (') or double quote (") character followed by the URI itself, followed by an optional single quote (') or double quote (") character followed by optional whitespace followed by ')'.
CSS 2.1, Section 4.3.4, URLs and URIs
http://www.w3.org/TR/2006/WD-CSS21-20061106/syndata.html#value-def-uri
and same thing with CSS 2.0
http://www.w3.org/TR/1998/REC-CSS2-19980512/syndata.html#uri
So, according to CSS 2.x, it is perfectly correct, valid to have a whitespace between the ' and the ).

or
url('http://www.mozilla.org/images/feature-logos1.png' )
and not url( )|

Opera 9.20 and Safari 2.0.4 succeed in all 4 alerts; MSIE 7 succeeds in the last (involving querying style.backgroundImage) 2 alerts.

This bug may be more about parsing url('...' ) than about background-image. It would be revealing to test some node having cursor: url('...' ) as well. Hmm...
