Bug 122648 – Assertion failure in -[WebBasePluginPackage dealloc] when two symlinks point to the same plugin

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

[Adam Roben (:aroben)]

My /Library/Internet Plug-Ins contains this:

lrwxr-xr-x  1 root    wheel    92 Jul 18  2012 AmazonMP3DownloaderPlugin.plugin -> /Applications/Amazon MP3 Downloader.app/Contents/Resources//AmazonMP3DownloaderPlugin.plugin
lrwxr-xr-x  1 root  wheel  91 Aug  7  2012 AmazonMP3DownloaderPlugin1017265.plugin -> /Applications/Amazon MP3 Downloader.app/Contents/Resources/AmazonMP3DownloaderPlugin.plugin

This causes an assertion failure in -[WebBasePluginPackage dealloc]:

    ASSERT(!pluginDatabases || [pluginDatabases count] == 0);

I believe this assertion is harmless in this case. The plugin is not actually part of any plugin database, despite thinking it is; -[WebPluginDatabase _addPlugin:] ensures that we only have one plugin for each canonical path.

I'm working on a patch and test for this.
