Deploying Signed Application to Samsung Honeycomb tablet failing

All,

We have an application for Tablets that works fine when not deployed as a signed application. I can run the app from Eclipse to the Samsung tablet and everything works fine. Soon as I create a signed application I get the following error (stack trace at bottom):

Question: why is it doing this - I cannot make a signed app to give to others on my team to test - nor to the customer. It's driving me crazy - the Fragment that it says it can't find, is there - and note that I'm using the compatibility jar with a min sdk level of 10.

The error makes no sense - if the XML was at fault or the Fragment class didn't exist as it states, it could never run on my table from Eclipse in developer mode. I'm perplexed - and it's halted our development effort as a result...

Oh, just for the record:

Eclipse 3.6.2 Mac OS X 10.7 Lion Samsung Galaxy Tablet 10.1 with Android version 3.1

Any pointers would be greatly appreciated...

Here's the relevant part of the Manifest:

<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.twoguysmedia.puzzleSliderTab"
android:versionCode="2"
android:versionName="1.1.20"
android:installLocation="auto">
<uses-sdk
    android:minSdkVersion="4"
    android:targetSdkVersion="11" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />   
<uses-permission android:name="android.permission.GET_TASKS" />

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.SEND_SMS"/>

...

and here's the exception stack trace:

For those who are wondering how this was solved - it turns out it's a minSDK issue - since the minimum SDK was less than the compiled SDK and the device was less than the compiled SDK, it allowed the app to be installed, but not run - thus the dump. The solution is to go back to the project and compile it at the level of the device to which it's being deployed - which kinda defeats the whole minSDK thing - wasn't that supposed to catch that problem?

Everything works fine now, anyway...
