[svn-r11176] Purpose:

    Bug fix

Description:
    Correct problems when querying information about a group that was opened
by dereferencing an object reference.

Solution:
    Read in symbol table information instead of rely on it being cached.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Too minor to require h5committest
