Cheese 无法启动：断言‘CHEESE_IS_CAMERA_DEVICE (设备)’失败

Cheese (photobooth) 以前在运行 Ubuntu 12.04 的 iMac 12,2 上可以正常打开，但现在无法从启动器或终端打开。我以为这可能是由于运行 WMII 导致的，但我登录到 unity 并从启动器和终端运行它，仍然没有成功。终端输出为：

Gtk-Message: Not loading module "atk-bridge": The functionality is provided by GTK natively. Please try to not load it.

这让我认为最后一行是导致它无法启动的原因，但我毫无头绪。我尝试使用“sudo apt-get --purge remove cheese”删除它，然后重新安装，但它仍然在启动时崩溃。网络摄像头仍然有效，因为当我使用“guvcview”时，网络摄像头显示正常。

不幸的是，看起来 Launchpad 上存在一个与此相关的错误，目前尚无解决方案。 https://bugs.launchpad.net/ubuntu/+source/cheese/+bug/930128

我在 Ubuntu 论坛上看到了另一个关于此问题的帖子，但他们的解决方案几乎不是一个“解决方案”： http://ubuntuforums.org/showthread.php?t=1969336

答案2

偶尔我也会遇到同样的问题。通常是在运行桌面几周后。这肯定是一个错误，但是我重新插入 USB 摄像头后，一切都正常。重新启动也可以。
