cannot encrypt files with seahorse-nautilus

[mc4man]

At least here nothing happens, just an extended warning -

** (seahorse-tool:14708): WARNING **: couldn't load all the keys (1/2) from GPGME

(seahorse-tool:14708): GLib-WARNING **: GChildWatchSource: Exit status of a child process was requested but ECHILD was received by waitpid(). Most likely the process is ignoring SIGCHLD, or some other thread is invoking waitpid() with a nonpositive first argument; either behavior can break applications that use g_child_watch_add()/g_spawn_sync() either directly or indirectly.

fixed with small patch to seahorse-nautilus
