If I "select * from horde_prefs" in the "SQL Shell" provided under  
"Administration" I see a result of the pref_uid, pref_scope,  
pref_name, and pref_value.  But in the display all the pref_value  
values are empty/blank.  Does the shell not display BYTEA values or  
does this indicate that Horde is unable to parse the values of those  
columns?

My other Horde instances do display values in the pref_value when I do  
the same thing.  BUt those instances are 4.0.10
