自从更新到 Ubuntu 14.04 以来，我在运行 GNUcash 时开始收到此错误消息。GNUcash 说这与他们无关，他们建议向 Ubuntu 寻求帮助。
那么有人可以帮助解决这个消息吗：
Gtk-Message: Failed to load module "overlay-scrollbar"
Gtk-Message: Failed to load module "unity-gtk-module"
(npviewer.bin:18843): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
还有更多，但只是一遍又一遍地重复相同的台词。
我还发现这些错误信息可能有助于别人找到解决办法！

答案1
这信息行意味着您缺少overlay-scrollbar-gtk2和unity-gtk2-module包。
这警告是因为你显然丢失了gtk2-engines-murrine包裹。
