More details, please.  I mean, it's set to sigusr2 by default and I get
a *Backtrace* buffer with "kill -SIGUSR2 <emacs_pid>".  But how does
that help with the "emacsclient <file>" invocation?

Anyway, I'm sure you know where I have to set a breakpoint in order to
find out where and for which function "Wrong number of arguments" is
signalled, right?

Bye,
