Android :: LinearLayout Stack Overflow Fails On 1.5 - Ok On 1.6?

I'm trying to make a horizontal layout with two TextViews, one should take up 40% of available width, the other 60%. This works unless the text is longer than available space, then a stack overflow exception is thrown. Pasting this into an empty 1.5 project xml file should cause it (though this seems to work ok on 1.6+):

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:weightSum="100" >

<TextView android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="40" android:text="Some really long sentence AAAAA" android:singleLine="true" />

<TextView android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="60" android:text="Some really long sentence BBBBB" android:singleLine="true" /> </LinearLayout>
Is there some other way to do this? I need to just break a row up into these separate columns with specific widths. I'm ok with the text just getting truncated on overflow,
