Sorry, seem i tested too fast here.

What is broke is not the new search bar, but the libephywebextension.so
which is unrelated with the search bar.

This extension is injected into the WebProcess and is used for things
like remembering passwords on sites (the typical login form)


Also you can check how libephywebextension.so only loads into the
WebKitWebProcess pid map if it can resolve the linker reference to
libdazzle.

It seems that in the linking process this .so library got linked with
the system libdazzle by mistake.


So the fix is either to declare a dependecy on the system libdazzle or
rebuild this library declaring a build-conflicts with the system
libdazzle to avoid this .so linking with it (instead the package embeded
copy of libdazzle)

$ ldd /usr/lib/x86_64-linux-gnu/epiphany-browser/web-extensions/libephywebextension.so|grep -i dazz
	libdazzle-1.0.so.0 => not found


$ apt-cache policy epiphany-browser
