Valgrind log from gucharmap

Description of problem:
When I look at the Hangul Jamo (U+1100 through U+11FF) in gucharmap, many of them render as boxes containing numbers between 0000 and 00FF.  Dragging across them with the right mouse button sometimes causes the specific numbers to change.  I re-ran gucharmap under valgrind and got lots of errors.  I get similar behavior by entering a few jamo in gedit with Ctrl-Shift-U, so I don't think the bug is with gucharmap.  I may be missing a font, but in that case pango should just show boxes with the 11xx numbers instead of behaving in this bizarre way.

Version-Release number of selected component (if applicable):
pango-1.28.1-4.fc14

How reproducible:
Always

Steps to Reproduce:
1. valgrind gucharmap
2. Choose View -> By Unicode Block.
3. Choose the Hangul Jamo block.
4. Right-drag across the characters.
  
Actual results:
Some boxes containing 00xx which change unpredictably, and valgrind errors.

Expected results:
Correct rendering or correct numerical boxes, with no valgrind errors.
