            Bug ID: 164103
           Summary: PluginInfoStore::loadPluginsIfNecessary can still load
                    plugins multiple times
    Classification: Unclassified
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Plug-ins
          Assignee: webkit-unassigned at lists.webkit.org

PluginInfoStore::loadPluginsIfNecessary is trying hard to make sure plugin paths are unique, but it's possible for two unique paths to refer to the same directory. For instance, on Arch, /usr/lib64 is a symlink to /usr/lib. So all plugins that we find when scanning /usr/lib64/mozilla/plugins/ get found again when scanning /usr/lib/mozilla/plugins/ because it's the same directory.
