根据您提供的调用堆栈信息，您的代码似乎在调用 `g_dbus_proxy_call_sync` 函数时遇到了问题。

根据堆栈信息，问题可能出在 `g_variant_type_info_get_type_string` 函数，该函数在 `libglib-2.0.so.0` 库中。这表明可能与 `GVariant` 类型相关的问题。

为了更好地帮助您解决问题，可能需要更多的上下文信息，例如完整的代码或更详细的堆栈跟踪信息。如果可能，请提供更多的代码或相关的上下文，以便我可以更好地理解和帮助您解决问题。

另外，请确保您的 GLib 和 GIO 库的版本是最新的，并且正确安装和链接到您的项目中。

请提供更多信息，以便我能够更好地帮助您。谢谢！

需要注意的是，上述代码中的私钥字节数组、摘要算法和加密算法等信息需要根据具体情况进行修改和替换。同时，在实际应用中，还需要考虑异常处理、安全性等方面的问题。
