org.xmlpull.v1.XmlPullParserException for "invalid drawable tag bitmap"

Ok, that's weird.

I've received this error for one of my activities, the weird thing is that the bitmap is used in every Activity! I don't even know how to reproduce the exception, it's working fine for me (and others I think).

This is the whole stacktrace:

The "missing" resource is this one (inside drawable folder):

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
        android:src="@drawable/bg"
        android:tileMode="repeat" />

The "bg" drawable is inside drawable-hdpi (could be that a problem?), but as I said it's used in every activity as background!

The error is called during the setting of the layout:

setContentView(R.layout.archivio);

The xml layout is this one:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent">

    <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="BLABLABLA"
            android:id="@+id/archivioTextView" android:layout_gravity="center_horizontal"
            android:gravity="center_horizontal" android:textIsSelectable="false" android:layout_marginTop="10dp"
            android:layout_marginBottom="10dp" android:layout_marginRight="30dp" android:layout_marginLeft="30dp"/>
    <ListView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/listaVeicoli" android:layout_gravity="center" android:drawSelectorOnTop="false"/>
</LinearLayout>

(Some of the useless statements are put by the Designer of IntelliJ!)

I've looked for similar problems but I don't have "strange" id like @+id/list or other problems that other users encuntered..

Any help on this? What am I missing? Thanks
