[Android] Game crash after hit the Home button

Hi everyone !

My game built with Unity 3.5.3f3 on a Samsung Galaxy S crash when I hit the HOME button on specific parts of the game.

Here's my logcat output :

I guess my crash comes from this lines (especially the first one) :

 07-20 09:53:34.258: D/PhoneWindow(28305): couldn't save which view has focus because the focused view com.unity3d.player.UnityPlayer$17@481af088 has no id.

I'm using EzGUI so I tried this solution but it didn't work.

I also tried this solution but it still not working.

I'm completely clueless on this problem. Could it be a memory problem ? (my game uses a lot of RAM but i don't have a better device to test my app with) What is this Sensor Listener ? I couldn't find on the web what does it mean.
