Detail sections not displayed with Crystal Reports 2010 Runtime (SP1 also)

Question

I have migrated a VB app from RDC 9 to Crystal Reports 2010 and I'm experiencing a very strange issue.
In a report with 6 nested groups, the detail part is splitted in 7 section, and the whole detail has the "keep together" flag activated. At runtime, some detail sections are not displayed. There is no suppress condition on the detail section. The missed sections are those near bottom of the page. I suppose that when there is no room to print the section on the page and it should go on the next page, Crystal forget to display it.
I exported the report in Crystal format and reopened with Crystal Reports designer and the missed section are displayed.
The same report is displayed correctly using RDC 9.
If I show the group tree and select the missed section group, the section is correctly displayed on a separate preview page.
I've some screenshot to better demonstrate the problem.
I hoped SP1 will resolve the issue but unfortunately it didn't.

This issue has been escalated for a fix. tracking number is TE5000325237. For anyone wanting to attach to this thread with a similar issue, please note the behavior as decribed in the TE below. If the description does not match your issue exactly, please create a new thread.
Description - Steps to Reproduce;
1) Run the report in the CR 2008 designer - note the second page
2) Run the report in VS2010 app using CRVS2010 SP1:
CrystalReportViewer1.ReportSource = <path to report>
3) Look at page 2 and compare to page 2 from the CR2008 designer (also, see attached compare.jpg file which is a screen shot of both views) - note missing group on page 2
4) Export to PDF, DO, RTF - same issue
5) Print to printer using the viewer print button - same issue
6) Same issue print to printer using code:
Dim crReportDocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
crReportDocument.Load("C:\Crystal\Test\Forum tests\Alberto missing detail section\Crystal Issue\Distinta di Taglio CR 2010.rpt")
crReportDocument.PrintToPrinter(1, 1, 1, 2)
        MsgBox("Done")
7) Same issue print to printer using code:
Dim crReportDocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
crReportDocument.Load("C:\Crystal\Test\Forum tests\Alberto missing detail section\Crystal Issue\Distinta di Taglio CR 2010.rpt")
Dim rcd As ISCDReportClientDocument
        rcd = crReportDocument.ReportClientDocument
        rcd.PrintOutputController.PrintReport()
        MsgBox("Done")
8) Export to RPT file format - view this export in the CR2008 Designer - report looks as it should
9) Add report to the .NET2010 project. trying to view the repor tin the .NET2010 IDE results in .NET crashing.
