Sorry for not posting infos.

I'm using latest code from master, revision : (GIT 37631e6 master; 
x86_64-unknown-linux-gnu)

My linux distro : archlinux, 64 bits, gnome-shell 3.2.x

My gcc :

address@hidden objdir-blue]$ gcc --version
gcc (GCC) 4.6.2 20111125 (prerelease)

I'm using pan updated to this commit :

http://git.gnome.org/browse/pan2/commit/?id=37631e661d54643cabe4f3376b9cc18778a16f78

Reverting it helped me getting back my delete key to work.

I think I found guilty commit. Here is what I wrote directly to hmueller :

"It is this one, well, after reverting it, no more crashes.

http://git.gnome.org/browse/pan2/commit/?id=bc7803590ebfdcbbbbdfa2f7dbe24253838193c8

If it is applied, every single time I want to sent a reply or a message, 
pan crashes with this error :

address@hidden src]$ terminate called after throwing an instance of 
'std::length_error'
  what():  basic_string::resize"

So a 6 days old "regression" :(

No, 64 bits here.

Reverting commit bc7803590ebfdcbbbbdfa2f7dbe24253838193c8 fix the problem.
