bug#15135: 24.3; Weird behavior with dead chars

[georgesleyetidoux]

Hi,
I encounter an odd behavior using emacs under Linux. When I type a dead
key like ~ (dead-tilde) or ` (dead-grave) I get the error "<dead-tilde
is undefined>" (where dead-tilde is the name of the dead chars).

What is really weird is that if I open the keybinding help (C-h b) I can
then type everything correctly until I exit the current session.

I tried to launch emacs with -q parameter in case the problem was from
my personnal configuration but the problem persist.

I am using the bépo (dvorak for french) keyboard layout [0] but I have
the same error if I switch to the swiss-french layout.

Don't you mean, "under GNU/Linux"?

Thanks for reporting the bug.

We've had various reports of such problems, in the past.
Yours sounds like it's related to http://debbugs.gnu.org/14044 can you
look at this thread and see if it might help you track down the source
of the problem?

It sounds like a bad interaction with ibus.
Does someone know what might be going on with ibus?

Thanks to reply.

Disabling ibus did the trick.
Before that I tried to change the $LANG variable like the emacs wiki
recommend[0] but without success.

Just in case, I also tried to run `emacs -nw' and it works correctly even
if I enable the ibus support in sakura[1].

I will for the moment remove ibus from my system as I don't need it.

Hmm... we really need to figure out what's up with that.
Is anyone here remotely familiar with ibus?
