Bug #: 31215
           Summary: FOCA Free fails to start because of carriage return
                    entities in .net's machine.config?
           Product: Wine
           Version: 1.5.8
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

A user complained in http://forum.winehq.org/viewtopic.php?t=16143
that "FOCA Free" crashed on startup.

The app initially crashes with some weird mono error, so I tried 
'winetricks dotnet20'.

This prompted the app to crash with
  Unhandled Exception: System.IO.FileNotFoundException: Could not load file or
assembly 'System.Core, Version=3.5.0.0
so I tried 'winetricks dotnet35'.

After that, the app crashed with
System.Configuration.ConfigurationErrorsException: Unrecognized element.
(C:\windows\Microsoft.NET\Framework\v2.0.50727\Config\machine.config line 156)

Looking at that file, I saw that that line and all later lines ended with
a carriage return entity (ampersand # 13 ;).  Removing those entities let
the app start ok.  Verified that doing a clean install of .net 3.5 in
an empty .wine directory before installing the app gives the same result.

I tried to nail down when those bogus entities appeared by watching
that file as I installed the various prerequisites, and (aside from
having real CR's in it) it seemed clean right up through dotnet30sp1.
However, I can't always get dotnet35 to install... it often hangs.
So this bug report is somewhat incomplete.
