使用互联网链接和DocNav时出错

我正在运行Linux Mint 17.1 64位。
每当我想在块设计中看到某些IP的文档并单击“产品指南”时，终端中将显示此错误，并且不会打开任何内容：
QLocalSocket :: connectToServer：连接被拒绝
如果我手动打开DocNav然后尝试在其中打开一些文档
（进程：32366）：GLib-CRItiCAL **：g_slice_set_config：断言'sys_page_size == 0'失败
（firefox：32366）：GLib-GObject-WARNING **：在初始化类后尝试添加属性GnomeProgram :: sm-connect
（firefox：32366）：GLib-GObject-WARNING **：在初始化类后尝试添加属性GnomeProgram :: show-crash-dialog
（firefox：32366）：GLib-GObject-WARNING **：在初始化类后尝试添加属性GnomeProgram :: display
（firefox：32366）：GLib-GObject-WARNING **：在初始化类后尝试添加属性GnomeProgram :: default-icon
并且它说Firefox已经在运行，所以为了让thar工作，我需要关闭所有Firefox窗口，这是不可接受的。
我已经尝试过这个我在某个地方看到的解决方案但是没有起作用：
cd /opt/Xilinx/SDK/2013.4/lib/lin64
sudo mv libstdc ++。so.6 libstdc ++。so.6.orig
它没有用。
有人能帮我吗？



以下为原文

I'm running on Linux Mint 17.1 64-bits.

Whenever i want to see the documentation of some IP in the block design and click in "Product Guide", this error appears in the terminal and nothing opens:
QLocalSocket::connectToServer: Connection refusedIf I open DocNav manually and then try to open some document within it
(process:32366): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed(firefox:32366): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::sm-connect after class was initialised(firefox:32366): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::show-crash-dialog after class was initialised(firefox:32366): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::display after class was initialised(firefox:32366): GLib-GObject-WARNING **: Attempt to add property GnomeProgram::default-icon after class was initialised and it says that Firefox is already running, so in order for thar to work I need to close all the Firefox windows, which is not acceptable.

I already tried this solution that I saw somewhere but that didn't function:
cd /opt/Xilinx/SDK/2013.4/lib/lin64sudo mv libstdc++.so.6 libstdc++.so.6.orig
And it didn't work.

Can someone help me?
