FlotChartContainer in paused activity causes crash

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Put a FlotChartContainer in an activity inside TabHost.
2. Show the tab.
3. Start another activity: startActivity(intent);
4. Press BACK.

What is the expected output? What do you see instead?
Should see FlotChartContainer. Instead, it crashes at:
FlotChartContainer(SurfaceView).updateWindow(boolean, boolean) line: 564    
FlotChartContainer(SurfaceView).onWindowVisibilityChanged(int) line: 213    
FlotChartContainer(View).dispatchWindowVisibilityChanged(int) line: 4027    

What version of the product are you using? On what operating system?
1.0

Please provide any additional information below.
Switching between activities inside a TabHost does not destroy them. Instead it 
pauses/resumes them. FlotChartContainer does not handle "pause" and "resume" 
events properly!

Crash occurs when drawThread.start() is called:

public void surfaceCreated(SurfaceHolder holder) {
    // TODO Auto-generated method stub
    drawThread.setRunning(true);
    drawThread.start(); // <------ boom!
}

Here's a hint: surfaceDestroyed is NOT called when Activity is inside TabHost!
