Android: Can not perform this action after onSaveInstanceState
<p>I'm still apparently not clear on handling fragments along with other things going on in my activity. The following is the stack trace:</p>

<pre><code>java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=2, result=-1, data=Intent { (has extras) }} to activity {com.ghcssoftware.gedstar/com.ghcssoftware.gedstar.GedStar}: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

<p>So this looks like it is my call to popBackStack within this function where I'm cleaning out any stacked fragments in one of my view panes:</p>

<pre><code>    // Pop fragments from second pane
    private void popStack() {
        if (mDualPane &amp;&amp; mBottomId &gt;= 0) {
            mViewTab.getTabHelper().tabGetFragManager().popBackStack(mBottomId, 
                    FragmentManager.POP_BACK_STACK_INCLUSIVE);
            mBottomId = -1;
        }
    }
</code></pre>

<p>Mainly I'm not sure why any of this is occurring "after onSaveInstanceState" has been called, or if that's what's really happening. Any possible explanations? Would popBackStackImmediate make a difference?</p>

<p>For what it's worth, I have not been able to recreate the circumstances in my testing, so it's only showing up in the reports.</p>
