Since two months ago it's been happening some strange crashes on Spotify in my iPod Touch 4th gen. It only happens when I'm hearing to music, the device is locked (now I'm on iOS 5.0.1) so the screen is off. When I make a double click on the Home button, for turning to the next song, it usually crashes and the app closes. Instead, if I only make one click on the Home button, I can unlock and go to the next song directly in the Spotify app. I tried reinstalling, deleting offline content (I have so many songs in offline, nearly 20 GB) but the problem continues. Something similar happened to anyone?
