Trouble entering composed characters

[Nikolaus Rath <Nikolaus@rath.org>]

Hello,

I have trouble entering keyboard compositions in many, but not all
applications. For example, when entering dead_iota + a (which I have
configured to give adiaresis in ~/.XCompose) gnome terminal just beeps
and does nothing. Other affected applications are gedit, icedove and
LibreOffice. Emacs, on the other hand, does not show any problems and
correctly inserts adiaresis.

When running xev in the terminal, everything looks alright:

Locales are

$ locale
LANG=en_US.utf8
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=


And the compositions are:

$ cat .XCompose 
include "/usr/share/X11/locale/en_US.UTF-8/Compose"

<dead_iota> <space>         	: ","   comma
<dead_iota> <A>                	: "Ä"   Adiaeresis
<dead_iota> <O>             	: "Ö"   Odiaeresis # LATIN CAPITAL LETTER O WITH DIAERESIS
<dead_iota> <U>             	: "Ü"   Udiaeresis # LATIN CAPITAL LETTER U WITH DIAERESIS
<dead_iota> <a>             	: "ä"   adiaeresis # LATIN SMALL LETTER A WITH DIAERESIS
<dead_iota> <o>             	: "ö"   odiaeresis # LATIN SMALL LETTER O WITH DIAERESIS
<dead_iota> <u>       		: "ü"   udiaeresis # LATIN SMALL LETTER U WITH DIAERESIS
<dead_iota> <s>               	: "ß"   ssharp # LATIN SMALL LETTER SHARP S
<dead_iota> <0>               	: "°"   degree # DEGREE SIGN



Does anyone have a suggestion how I can track this down further? I am
using Debian testing.


Thanks,
