Ok, I contacted upstream (Paolo) and they said this is intentional, and not a bug:
"yes this is intentional, the arrow is meant to be shown only when there is not enough space to show all the launchers, if the applet shows the launcher instead of the arrow this means that there is the space to show all the launchers, in this case showing the arrow wouldn't save any space because the arrow is of the same size or bigger than the single launcher you are trying to hide." -- Applet does not respect a size of 1 with 2 items https://bugs.launchpad.net/bugs/472918 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
