Bug 35285 – [GTK] Crashes when disposing a WebKitWebView inside the Flash plugin

• Status: RESOLVED
• Resolution: INVALID
• Component: Plug-ins

[Sebastian Dröge (slomo)]

Hi,
Webkit/GTK (GIT as of two days ago) often crashes when disposing a web view. The crash is inside the Flash plugin but I guess it happens because the Flash plugin accesses some memory which was already destroyed. Maybe the plugins should be destroyed before anything else.
