Xcode Organizer：无法使用iPhone(dyld_shared_cache_extract_dylibs失败)

当我插入iPhone并启动 Xcode管理器时,设备旁边的黄色圆圈显示“此设备正忙或Xcode无法使用”.
组织者然后处理两个文件(第二个文件需要很长时间才能完成),然后我收到错误消息,如屏幕截图所示.

我试图谷歌的错误消息(“dyld_shared_cache_extract_dylibs失败”),但找不到任何有用的东西.
我尝试了几件事：修复我的硬盘驱动器的权限并运行“sudo update_dyld_shared_cache -force”.仍然收到错误消息.

我正在运行iOS 4.2.1和Xcode 3.2.5.从4.2更新到4.2.1(我认为)后,我没有更新Xcode.

Xcode控制台是空的,但常规OS X控制台显示：

然后不断重复此错误消息.

解决方法

值得的是：当我没有磁盘空间时遇到了这个问题.似乎XCode是第一个通过抛出此错误来“注意”的应用程序.释放一些磁盘空间后,一切都恢复正常.
