Copy and paste the output of that call into your bug report. This process is described in more detail in the Debugging chapter of the OpenLaszlo Developer's Guide.

In general, OpenLaszlo 4.0.6 begins a new strategy, where we intend to offer point releases more frequently to address specific bug fixes. By looking at JIRA, you will see that many bugs are fixed in trunk (4.x), our active development branch. However, we understand that many people aren't comfortable moving to the latest, less stable development branch, so we are going to spin more frequent releases from the 4.0.x branch to provide qualified releases of significant bug fixes more quickly to the community. The next point release is named "Cranberry" and you can view the bug fixes currently scheduled for it on the OpenLaszlo Roadmap in JIRA. You can preview the Cranberry release by downloading of the 4.0.x nightly builds.
Support for DHTML applications remains at "beta" level; it will be fully supported with OL 4.1. Until then, you can find the most recent DHTML bug fixes and support in the trunk branch (4.x nightly builds).
If you missed their talk at AjaxWorld, you can still read about how Benjamin Shine and Bret Simister built an iPhone application in OpenLaszlo at iPhoneDevCamp in two days.
The iPhone application is NEWSMATCH. It’s a game that presents items from a Yahoo! News RSS feed, with images and titles. The challenge is to match an image with the headline it illustrates. To play, you click(or tap) on an image, then click (or tap) on a headline. If they match, you’re given the opportunity to read the story. Try it!
See their OpenLaszlo blog entry, and walk through the progression of NEWSMATCH, illustrating how OpenLaszlo facilitates rapid development of iPhone applications. NEWSMATCH was written from scratch in two days, using OpenLaszlo. It ran on the iPhone, with very few iPhone-specific modifications, from the very first versions.
