Do you have a reference bug on bugzilla?

This is definitely wrong. QtWebKit-2.1, as generated from the sources,
should be qtwebkit-2.1.0. It could be versioned as qt-4.8.X only if
imported to and built from qt sources.
I've found the version 4.8.0 in WebKit/qt/qt_webkit_version.pri...
Actually, the patch changing it is yours, back then in May :-) I guess
the version was set as a placeholder but nobody remembered of it
existence later on.

I'm not very familiar with symbian, but we have a similar problem with
the lib soname on linux: the soname is currently libQtWebKit.so.4 and
the file is libQtWebKit.so.4.8.0...
So we don't have much choice... we could:
1. Change the project version everywhere to something like 20.x;
2. Keep the version as 2.x but internally use 20.x (not so internally,
users will be exposed to it)
Option (1) is the technically correct choice, but option (2) is far
less painful right now.
My suggestion is to adopt option (2) by now and later move to (1) -
the migration will not break anything.
Please let me know if there's a bug reference for that, otherwise I'll
open one myself.
Thanks for bringing this up.
