Thanks to TransTech we've got a .wgt file. It doesn't work yet, but at least there's a log. Attaching the .wgt and a screenshot from NokiaWebSDK 1.0.1 from wiki.meego. (the gzipped png is a high resolution version)
Does anybody know how can we fix these errors?
EDIT: the .wgt is too big for attachment. It's here:

For running this qtwrt is required

PS. I tried Chromium from the post above, no success. Chromium v6 is slow but the app runs. Thanks anyway.
