Like I told you on IRC, it must be something local.

Qt 3.3.8:
$ strace -fF -eopen konsole 2>&1|grep ompose
open("/home/tmacieir/.XCompose", O_RDONLY) = -1 ENOENT (No such file or 
directory)
open("/usr/share/X11/locale/compose.dir", O_RDONLY) = 12
open("/usr/share/X11/locale/pt_BR.UTF-8/Compose", O_RDONLY) = 12
open("/home/tmacieir/.XCompose", O_RDONLY) = -1 ENOENT (No such file or 
directory)
open("/usr/share/X11/locale/compose.dir", O_RDONLY) = 12
open("/usr/share/X11/locale/pt_BR.UTF-8/Compose", O_RDONLY) = 12

Qt 4.4.0/4.4.1:
$ strace -fF -eopen ~/KDE4/bin/konsole 2>&1|grep ompose
[pid 25223] open("/home/tmacieir/.XCompose", O_RDONLY) = -1 ENOENT (No such 
file or directory)
[pid 25223] open("/usr/share/X11/locale/compose.dir", O_RDONLY) = 17
[pid 25223] open("/usr/share/X11/locale/pt_BR.UTF-8/Compose", O_RDONLY) = 17
[pid 25223] open("/home/tmacieir/.XCompose", O_RDONLY) = -1 ENOENT (No such 
file or directory)
[pid 25223] open("/usr/share/X11/locale/compose.dir", O_RDONLY) = 17
[pid 25223] open("/usr/share/X11/locale/pt_BR.UTF-8/Compose", O_RDONLY) = 17

There are no hits for "Compose" in Qt source code, so it is libX11's doing.
