Android SQLite onUpgrade = force close

Here is the situation. I'm upgrading my database adding a single column. The upgrade appears to go fine. I can see the new column added but the problem is when upgrading my app from the older to the new version w/ new DB I get force close. The force close seems to occur when accessing the new column. If I do a fresh install however I get no force closes and app works as expected.

My on upUpgrade looks as such:

  @Override   public void onUpgrade(SQLiteDatabase notes_db, int oldVersion, int newVersion) {    if (oldVersion == 29) {
    notes_db.execSQL("ALTER TABLE Notes ADD COLUMN Priority text");
    notes_db.execSQL("ALTER TABLE Todo ADD COLUMN Priority text");
    notes_db.execSQL("ALTER TABLE Todo_keys ADD COLUMN Priority text");    } else {
    notes_db.execSQL("DROP TABLE IF EXISTS " + NOTES_TABLE);
    notes_db.execSQL("DROP TABLE IF EXISTS " + TODO_TABLE);
    notes_db.execSQL("DROP TABLE IF EXISTS " + TODO_KEYS_TABLE);
    onCreate(notes_db);    }      }

Any ideas would be appreciated.

This is where I believe it fails...

Line 1065 is the catch statement and priority1 is the new column I added..

String priority1 = c.getString(c.getColumnIndex(databaseHelper.DB_COLUMN_PRIORITY));

        if (priority1.equals("Low")) {
            try {
                String low_pref = preferences.getString("low_priority_color", "Default");
                if (!low_pref.equals("Default")){
                    priority_text.setBackgroundColor(Integer.parseInt(low_pref, 16)+0xFF000000);
                    priority_text.setVisibility(View.VISIBLE);
                } else {
                    priority_text.setBackgroundColor(0xFFFFe640);
                    priority_text.setVisibility(View.VISIBLE);
                }} catch (Exception e) { 
                    errorText = e.getMessage();
                    themeError();
                }                   
            }

Fixed. New column had null value
