Weird problem

[René van den Berg]

I have a report and on some instances of this report I get an Object reference not set error. The preview shows method: [Pop], and no data is displayed so I cannot create a .mdc file. As I said it doesn't happen all the time. So there is a data dependency. If I remove a reportfooterband from my report, than the problem is solved.
If I make the same reportfooterband empty (so no components are on the band) than I also don't get an error. When I put an empty textcomponent on the reportfooter I get an error. I'm not certain but I think it has to do with the report not fitting on 1 page. But of course this is a wild guess. Any help would be appreciated. By the way. I use the latest version of StimulReport SR_2007.06.08_R2005, but I also tried the 2007.1 version.

This is the stack trace:
