I'm using Gnome3 on Ubuntu 13.10.
Above symptoms was causing me a crash at install at the call of "nspluginwrapper -a -v -u"

Removing the "Gnome Shell Integration" plugin solved this issue for me.

When I was running "nspluginwrapper -i " the "npwrapper.libplugins.so" was never installed, and the plugin I was trying to install was never recognized.

A traceback found that function "is_wrapper_plugin" in file "npw-config.c" called "void *handle = dlopen(plugin_path, RTLD_LAZY)" and seemed to cause the crash.
Call variable was: "plugin_path const char * 0x613390 "/usr/lib/mozilla/plugins/libgnome-shell-browser-plugin.so")

I just deleted /usr/lib/mozilla/plugins/libgnome-shell-browser-plugin.so
