RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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 .
