I have seven reports of this plugin process crash in WebKit::PluginDestructionProtector::PluginDestructionProtector. Problem is that pluginController is unexpectedly null: Truncated backtrace: Thread no. 1 (10 frames) #0 WebKit::PluginController::PluginDestructionProtector::PluginDestructionProtector at /usr/src/debug/webkitgtk-2.16.3/Source/WebKit2/WebProcess/Plugins/PluginController.h:165 #1 std::make_unique<WebKit::PluginController::PluginDestructionProtector, WebKit::PluginController*>(WebKit::PluginController*&&) at /usr/include/c++/6.3.1/bits/unique_ptr.h:791 #2 WebKit::PluginDestructionProtector::PluginDestructionProtector at /usr/src/debug/webkitgtk-2.16.3/Source/WebKit2/WebProcess/Plugins/Netscape/NetscapeBrowserFuncs.cpp:62 #3 WebKit::NPN_InvokeDefault at /usr/src/debug/webkitgtk-2.16.3/Source/WebKit2/WebProcess/Plugins/Netscape/NetscapeBrowserFuncs.cpp:687 #4 install_extension_cb at browser-plugin.c:478 #5 g_task_return_now at gtask.c:1121 #6 g_task_return at gtask.c:1179 #7 reply_cb at gdbusproxy.c:2583 #8 g_task_return_now at gtask.c:1121 #9 g_task_return at gtask.c:1179
