Some gtk dialogs do not accept mouse clicks when buttons remapped using xmodmap

[David]

After upgrading to oneiric I noticed that a few menus don't accept mouse clicks in some places any more. List-boxes inside tabs, as used by 'gnome-control-center sound' cannot be modified via mouse. Keyboard navigation still works though. Similar problem with gnome-terminal: when a terminal window is tabbed, mouse-selection of terminal contents is impossible. This seems to be caused by me using the command

  xmodmap -e 'pointer = 1 2 3 4'

after login, to remap the order of mouse buttons for left-handed use.

I just caught a little more insight into the problem: if I open up two gnome-terminal windows side-by-side, one tabbed, one without tabs, if I first click the first (non-tabbed) window, then change focus to the second window by clicking it, attempting to select any text in the second window, actually does select text in the first window, with the corresponding window-relative position. So events go to the wrong window. How's that possible? Maybe the window-manager is part of the bug? However, non-gtk applications like Emacs etc. do not show the problem, so I think it must be gtk-related.

For me that bug is pretty grave. Hope it can be reproduced on other installations.

Just noticed a typo in the description above. The command I use to remap the mouse buttons is this one:

 xmodmap -e 'pointer = 2 1 3 4'

I'm using the other command with args 'pointer = 1 2 3 4' using for getting back to default button order, which works around the reported bug.

Status changed to 'Confirmed' because the bug affects multiple users.

I'd like to point out: this is not an Ubuntu-specific bug: I'm a gentoo user, running fvwm as my wm, and I have the same problem. This is specific to GTK apps with multiple interactable fields (evince and audacious are affected).

Any guesses where upstream this is broken?
