           Summary: WebKit does not check Windows Registry HKEY_CURRENT_USER
                    for NPAPI plugin locations
           Product: WebKit
           Version: 522+ (nightly)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: vitorio.miliano at gemalto.com


Summary:

Safari 3 for Windows (tested against 3.0.2, 3.0.3 [522.15.5] and the latest
WebKit nightly [r25168]) only checks HKEY_LOCAL_MACHINE for NPAPI plugin
locations, not HKEY_CURRENT_USER, which means it does not find plugins that
were installed without Administrator priviledges.

http://developer.mozilla.org/en/docs/Plugins:_The_first_install_problem
explains that HKEY_CURRENT_USER\Software\MozillaPlugins is a valid location for
plugin data for non-Administrator installs.  Both locations should be checked.


Steps to Reproduce:

Install an NPAPI plugin in an arbitrary (and ostensibly
writeable-as-less-than-Adminstrator) location, e.g. on your Desktop.

Create a minimal HKEY_LOCAL_MACHINE registry entry for this plugin, e.g. by
running the following registry script:

----------
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\Software\MozillaPlugins\npsconnect at gemalto.com/SConnect;version=0.5.0.0]
"Path"="C:\\Documents and Settings\\vmiliano\\Desktop\\npsconnect.dll"
----------

Check Safari's "Installed Plug-ins" page and see the plugin listed.  Delete the
registry entry, reload the page and confirm the plugin is no longer listed.

Create a minimal HKEY_CURRENT_USER registry entry for the plugin, e.g. by
running the following registry script:

----------
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\MozillaPlugins\npsconnect at gemalto.com/SConnect;version=0.5.0.0]
"Path"="C:\\Documents and Settings\\vmiliano\\Desktop\\npsconnect.dll"
----------

Check Safari's "Installed Plug-ins" page and see that the plugin is NOT listed.


Expected Results:

The plugin should be found whether the plugin is installed in
HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER.


Actual Results:

The plugin is only found when installed in HKEY_LOCAL_MACHINE, requiring
Administrator access.


Regression:

Occurs in Safari 3.0.2, 3.0.3, and in the latest WebKit nightly build (r25168,
