What does the 'Failed to move application. Not enough memory' error mean when choosing 'Move to SD card'? When I choose 'Settings - Applications - Manage applications' , and a 'Move to SD card' I get the 'Failed to move application. Not enough memory' error.

Anyone know why ?

I am running Froyo 2.2 on a Samsung Galaxy S phone.

I have 1.7GB free of system memory and 13.1 GB internal memory free on the internal SD card.

*UPDATE *

Can someone with an Galaxy S phone please confirm this ? I have seen it on two phones, and really would like to know what's happening here.
This is a known problem with leaked 2.2 Galaxy S Vibrant software (happened to me).  Even if you're not using a Vibrant I would suspect the issue is the same, since the software is mostly the same.

You can fix it using this post at XDA if you have a Vibrant or i9000.  If you have another model just check the subforum for your device (or take a risk and try this anyways).
