Dialer Activity is crashing sometimes on the LG GT 540 running 2.1

This seams to happen maybe one time in 10 only on a older phone (LG GT 540 running 2.1) The newer phones don't appear to have this issue.

Im launching the activity in the usual way:

Uri uri = Uri.parse("tel:4444");
Intent callIntent = new Intent(Intent.ACTION_DIAL, uri);
startActivity(callIntent);

The crash log would report the dialier app (not my app) crashed:
