[android-developers] Dialog dismiss()

I keep getting this crash report from my users:

java.lang.IllegalArgumentException: View not attached to window manager
at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:355)
at android.view.WindowManagerImpl.removeView(WindowManagerImpl.java:200)

at dalvik.system.NativeStart.main(Native Method)

I don't know if it's any one particular Activity causing the issue,
none of my code appear in the stack trace.. but my typical pattern
looks like this:

private void getCurrentGames()
{
if( this != null )
{
progressDialog = ProgressDialog.show( this, "Working . . .",
"Getting current games.." );
}

new Thread()
{
@Override
public void run()
{
getCurrentGames();
handler.post( updateCurrentGames );

if( this != null && progressDialog != null )
{
try
{
progressDialog.dismiss();
}
catch( Exception e )
{
}
}
}
}.start();
}

How can I keep my dismiss() calls from blowing up? Why doesn't try/catch work?
