Good news: I think I fixed both the stop button crashes in webkit-eal and most of the on-screen keyboard issues with libwebkit, including copy-paste and editing existing text with the full screen keyboard.

New webkit-eal package is here, see the changes file or garage svn for details.

New libwebkit package is here, that diff is against webkit revision 41128 with bundyo's patch applied. (This also disables most advanced HTML5 features which are enabled in bundyo's build).

Please let me know how this is working for you! Also, let me know what features you're missing for the next major release. I guess it'll be mostly more and better gconf backed options.
