Comment 7 for bug 167846

Testing r11550 (OS X 10.7.4, X11 backend):
with default gtk settings, it works as expected now.

However, with this gtk setting (via ~/.gtkrc-2.0):
  gtk-entry-select-on-focus = 0
pressing <TAB> after having typed a new width does not move the focus to the height entry, instead, focus is returned to the canvas (and typing a number may trigger a zoom shortcut). With that same gtk setting, tabbing (after 'Ctrl+A' and typing a new value) from X to Y, and from Y to W is ok, only the transition from W to H doesn't work as expected.

(Note: I'm aware that not selecting the content of the entry box when entering it is not a default setting - I only use it to prevent a crash when adding new layers (an unrelated bug limited to Inkscape using the Quartz backend of GTK+, probably upstream)).
