Bug#585505: seahorse-agent relies on default SIGCHLD handlers, but does not set them.

[Daniel Kahn Gillmor]

Package: seahorse
Version: 2.30.1-2
Severity: normal

If you exec seahorse-agent from another process which has decided to
ignore the SIGCHLD signal, glib produces the following warning to
stderr:

(seahorse-agent:2171): GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned. This is a bug in the program calling g_spawn_sync(); either don't request the exit status, or don't set the SIGCHLD action.

Presumably this means that seahorse-agent requires the default SIGCHLD
handler, but does not explicitly ask the system for it.

Early in its execution, seahorse-agent should detect if the action for
SIGCHLD is currently set to SIG_IGN, and reset it to SIG_DFL in that
case.
