Description of problem:
I have done two clean installs of Fedora 11, x86_64 and i386 respectively. 
Both are using "Traditional Chinese" during the install process and apply the
latest update after installation.

I take a look at the font size and DPI setting on both of them and they are the
same as listed below:
應用程式字型:Sans,10
文件字型:    Sans,10
桌面字型:    Sans,14
視窗標題字型:Sans Bold 10
固定寬度字型:Monospace 10
解析度:96 DPI

Then I open "gucharmap" and search the character "糓" (U+7CD4).
Change the font size to 12, 11 and 10.

The i386 version works quite well.

However, the display on the x86_64 one become messy.
And the following warning message appear on the terminal:
(gucharmap:1997): Pango-WARNING **: shaping failure, expect ugly output.
shape-engine='BasicEngineFc', font='AR PL UMing HK Light 12', text='糔'

(gucharmap:1997): Pango-WARNING **: shaping failure, expect ugly output.
shape-engine='BasicEngineFc', font='AR PL UMing HK Light 11', text='糔'

(gucharmap:1997): Pango-WARNING **: shaping failure, expect ugly output.
shape-engine='BasicEngineFc', font='AR PL UMing HK Light 9.9990234375',
text='糔'  

Version-Release number of selected component (if applicable):


How reproducible:
Always in x86_64

Steps to Reproduce:
1. open "gucharmap" and 
2. search the character "糔" (U+7CD4).
3. Change the font size to 12, 11 and 10.


Actual results:
Display on the x86_64 one become messy.
And the following warning message appear on the terminal:
(gucharmap:1997): Pango-WARNING **: shaping failure, expect ugly output.
shape-engine='BasicEngineFc', font='AR PL UMing HK Light 12', text='糔'

(gucharmap:1997): Pango-WARNING **: shaping failure, expect ugly output.
shape-engine='BasicEngineFc', font='AR PL UMing HK Light 11', text='糔'

(gucharmap:1997): Pango-WARNING **: shaping failure, expect ugly output.
shape-engine='BasicEngineFc', font='AR PL UMing HK Light 9.9990234375',
text='糔'  


Expected results:
Character '糔' should be displayed properly without triggering Pango warning.
