Comment 15 Michael Catanzaro 2016-06-28 21:00:26 UTC
Some random gsettings key ("cursor-blink-timeout") changed on the schema org.gnome.desktop.interface, triggering the on_schema_change callback that calls update_clock. But priv->timezone is NULL at the time, and update_clock is not prepared to handle that case, causing the crash when it's passed to g_date_time_new_now.

Problem is, priv->timezone should never be NULL there and I don't see how it could have happened. priv->timezone is initialized in _init and can't possibly become invalid until the wall clock is finalized, but by that point the settings watch would have already been disconnected (by unreffing the GSettings object in dispose) and so on_schema_changed could never be called. It might be a bit safer to use g_signal_connect_object there, but it shouldn't matter since nothing else ever refs the GSettings object. So I don't see it.

Comment 16 Fedora End Of Life 2017-07-25 21:23:00 UTC
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 17 Fedora End Of Life 2017-08-08 15:07:21 UTC
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
