Description Dalibor Pospíšil 2014-04-28 15:13:28 UTC

+++ This bug was initially created as a clone of Bug #981580 +++

Description of problem:
seahorse-tool is not working.

Version-Release number of selected component (if applicable):
glib2-2.36.3-5.el7.x86_64
seahorse-nautilus-3.8.0-4.el7.x86_64

How reproducible:
Just try installing it and encrypting some text file.

Actual results:
seahorse-tool -e test.txt 

** (seahorse-tool:19339): WARNING **: couldn't load all the keys (1/2) from GPGME

(seahorse-tool:19339): 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.


Expected results:
it should just work

I am wondering whether this problem also impacts other components beside seahorse-nautilus.

It also broke Pidgen -- see the GNOME bug under External Trackers.

Comment 5 Colin Walters 2014-04-30 14:46:53 UTC

I do plan to rebase glib2 for 7.1.

I know it is mentioned in the upstream bug but I didn't find such a bug reported against RHEL-7.

Comment 8 Colin Walters 2014-04-30 16:20:53 UTC

This commit should be backported to seahorse-nautilus first:
https://git.gnome.org/browse/seahorse-nautilus/commit/?id=c41f07cf5785b2d755b85f20bf0546c6ce2ebb02

Comment 9 Colin Walters 2014-04-30 16:22:15 UTC

For pidgin, the should not both have their own SIGCHLD handler *and* use GLib's g_spawn().  They're mutually exclusive.

I'd suggest Pidign should drop their SIGCHLD handler and just use g_child_watch_add().

Comment 10 Stef Walter 2014-05-01 19:47:14 UTC

There's a work around patch for seahorse-nautilus here, which could be shipped in my opinion:

https://bugzilla.gnome.org/show_bug.cgi?id=697895
https://bug697895.bugzilla-attachments.gnome.org/attachment.cgi?id=251918

Rui is the RHEL/Fedora maintainer of seahorse-nautilus.

Comment 12 Colin Walters 2014-12-16 14:03:23 UTC

This should be fixed by the rebase in bug 1104372 .
