Zsh 4.3.12: subshell in midnight commander: precmd: 15: bad file descriptor

[Pavel Reznicek <reznicek@xxxxxxxxxxxxxxxxxxxxxx>]

Hello,

  after upgrading to zsh 4.3.12 (in debian), I am having problems running 
midnight commander in zsh (going back to zsh version 4.3.10 it works 
fine). The symptom is that when trying to use the subshell in mc, it 
complains about:

precmd: 15: bad file descriptor

and the mc session get hanged. Of course it could be bug in mc and not 
zsh, but since this behaviour is not seen with zsh 4.3.10, the zsh updates 
since that version can tell what is going on. Browsing the mc source code, 
the precmd command defined in there is:

precmd(){ pwd>&%d;kill -STOP $$ }

Would some have an idea why this precmd command would cause the error 
message above in connection of the updateds between zsh 4.3.10 and 4.3.12 
?

PS: It is also important to note that the behaviour seem to be
    terminal-emulator dependent (happens in konsole and urxvt, but not in
    gnome-terminal, aterm).

Thanks,
Pavel
