Android Gallery app disappears on first boot

On vexpress, whilst testing a fix for bug #1086623 I noticed that on first boot the Gallery app would disappear from the Apps list shortly after boot (on subsequent boots the app appears OK as normal). I have also reproduced this on the 13.01 release image booted with a newer kernel so the new sdcard mounting fix is not directly the cause.

Whilst debugging I got as far as determining that if I enable DEBUG_LOADERS in packages/apps/Launcher2/src/com/android/launcher2/LauncherModel.java then the onReceive() method gives the log output:

D/Launcher.Model( 2875): onReceive intent=Intent { act=android.intent.action.PACKAGE_CHANGED dat=package:com.android.gallery3d flg=0x8000010 (has extras) }

and subsequently the updatePackage() method in
packages/apps/Launcher2/src/com/android/launcher2/AllAppsList.java
is being call with package "com.android.gallery3d" and it's matches variable has a ResolveInfo = {416cfd68 com.android.gallery3d.app.Gallery p=0 o=0 m=0x108000}]

and this section of code is removing the Gallery app.

                if (packageName.equals(component.getPackageName())) {
                    if (!findActivity(matches, component)) {
                        removed.add(applicationInfo);
