Bad split of chained method call expression

[SteveGilham]

Before

                             root.SetAttribute("driverVersion", "AltCover.Recorder " +
                                     System.Diagnostics.FileVersionInfo.GetVersionInfo(System.Reflection.Assembly.GetExecutingAssembly().Location).FileVersion)

After

            root.SetAttribute
                ("driverVersion", 
                 "AltCover.Recorder " 
                 + System.Diagnostics.FileVersionInfo.GetVersionInfo
                       (System.Reflection.Assembly.GetExecutingAssembly().Location).FileVersion) //  line 127

The first builds, the second goes
Base.fs(127,85):error FS0039: The field, constructor or member 'FileVersion' is not defined.
Base.fs(126,20): error FS0001: The type 'Diagnostics.FileVersionInfo' does not match the type 'string'

Another case of what might be the same problem:

Before:

type Exception with
        member inline __.FirstLine = 
            __.Message.Split([|Environment.NewLine|], StringSplitOptions.RemoveEmptyEntries).[0]

After:

type Exception with
        member inline __.FirstLine =
            __.Message.Split
                ([| Environment.NewLine |],
                 StringSplitOptions.RemoveEmptyEntries).[0]

Results in compile error:
The operator 'expr.[idx]' has been used on an object of indeterminate type based on information prior to this program point. Consider adding further type constraints

This issue is back in version 4.0.0, in the self-same piece of code
