This does not seem related at all. First, scim is linked to libstdc++6,
and this problem appears for any gtk applications, even the ones which
do not use c++ (for example gedit does not seem to be linked to
libstdc++ according to ldd).

Yes, only $HOME is on NFS. To be sure that the problem is not coming
from nfs, I put $HOME/.scim on my local dist through a soft link, but
maybe other directories in $HOME are involved, dunno.
Basically, I think this is a bug related to connecting to the socket. If
I "start fresh", that is I unset GTK_IM_MODULE (and XMODIFIERS and
XIM_INPUT) and do not automatically launch scim in my session, I then do
the following:
- start scim manually in a terminal (with scim -d)
- in the same terminal, I launch an application this way:
GTK_IM_MODULE=scim strace app
Any application hangs at the following call:
connect(17, {sa_family=AF_FILE, path="/tmp/scim-socket-frontend-david"},
33) = 0
After sometimes (around one minute, generally), the application
continues, but then the problem appears again when I want to use the
kanji configuration (at the same system call). After again sometimes,
the app continues, but without the kanji configuration.
Besides $HOME on NFS, the other thing which is really peticular in my
setup, and maybe related, is that I do not have any DNS server on my
network. All connection are done through a proxy (I have http_proxy set
to the proxy). Again, not sure it is related, but it also has been the
cause of problems with other softwares,
At this point, I am ready to use a debugging version of scim :)
