Bug#341240: libgtk2.0-0: Default input method "cedilla" incomplete, buggy and inconsistent with rest of system

[Lionel Elie Mamane]

Package: libgtk2.0-0
Version: 2.6.10-1
Severity: normal

I'm running with an fr_LU.UTF-8 locale and all GTK+2 applications
behave inconsistently with all other applications (QT apps, emacs,
xterm, ...) wrt to their handling of the compose key. Through
experimenting with Gnome Terminal, I found out that the default input
method is "cedilla"; if I select "X Input Method", things start to go
_much_ better. "X Input Method" should be the default, or cedilla
should be fixed, for reasons of desktop-wide uniformity.

Examples of cedilla breakage:

 - Compose+! ^ doesn't work (should give ¦)

 - When pressing Compose for more than a fraction of a second, you get
   a sequence of beeps and the compose sequence works only one time
   out of two. But if you are quick enough (before the first beep) or
   by mere chance hit the next key in the right timeslot, some of them
   work. E.g. Compose E ` or Compose E ^ work if you are quick
   enough. This is a significant challenge, as the compose sequences
   are often a bit complicated (3 keys together to do Compose+E for
   example), so giving people enough time is IMPORTANT.

 - Compose+o a doesn't work (should give å)

 - Compose+c c doesn't work (should give č)

My keyboard settings:

Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "keyboard"
        Option          "CoreKeyboard"
        Option          "XkbRules"      "xfree86"
        Option          "XkbModel"      "microsoft"
        Option          "XkbLayout"     "us"
        Option          "XkbOptions"    "altwin:left_meta_win,compose:rwin"
EndSection


Bonus Question: Would you know how to change the input method in an
arbitrary GTK+2 app? I could find it only for Gnome Terminal.
