[Bug 10275] New: "Get PLP" button in Matlab R14 installer does nothing

http://bugs.winehq.org/show_bug.cgi?id=10275

Summary: "Get PLP" button in Matlab R14 installer does nothing
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: Installer
          Severity: normal
          Priority: P2
         Component: wine-misc
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The Matlab R14 installer offers you a chance to retrieve
your personal license password via the web by clicking on a button
marked "Get My PLP".  Clicking on this does nothing.
+process shows what it's trying to do:

trace:process:CreateProcessW app (null) cmdline L"rundll32
url.dll,FileProtocolHandler http://www.mathworks.com/accesslogin/index.jsp"

+all on that commandline shows where it's going south:

0009:trace:nls:WideCharToMultiByte cp 0
L"http://www.mathworks.com/accesslogin/index.jsp%5C0000" ->
"http://www.mathworks.com/accesslogin/index.jsp%5Cx00", ret = 47
0009:Ret  KERNEL32.WideCharToMultiByte() retval=0000002f ret=7ecce7cd
0009:trace:rundll32:main Calling L"FileProtocolHandler"
(0x10024,0x7ecc0000,"http://www.mathworks.com/accesslogin/index.jsp%22,10)
0009:Call url.FileProtocolHandlerA(00010024,7ecc0000 "MZ\x90",0012b2e8)
ret=7ecceb72

I bet it'll be pretty easy to track down where that
argument gets mangled.
