The following change to webkit/webkitwebview.cpp webkit_web_view_open(): - gchar* fileUri = g_strdup_printf("file://%s", uri); + gchar* fileUri = g_filename_to_uri(uri, NULL, NULL); webkit_web_view_load_uri(webView, fileUri); causes corruption of the uri if it contains a named anchor ("/foo/bar#quux") rather than just a filename ("/foo/bar"). The use of named anchors with local filenames is common in devhelp, and this change thus breaks devhelp (reverts much of the problem solved in Bug #17176). If the given uri contains a named anchor, that needs to get carried as a named anchor (i.e., "#foo") into webkit_web_view_load_uri(). However, g_filename_to_uri() doesn't respect named anchors...it treats the whole given string as the pathname and uri-encodes it, thus converting the "#" to %23. The result is that w_v_l_uri gets "/foo/bar/%23quux", which is obviously not the intended filename. The solution is to parse apart the given uri: do g_filename_to_uri on the pathname part only and then re-append the anchor if there is one.
