Comment 14 Kevin Fenzi 2016-11-04 22:42:39 UTC
Can you duplicate the crash? Or it was a one time thing?

Comment 15 Mukundan Ragavan 2016-11-04 22:49:45 UTC
Any chance you were connecting/disconnecting external monitors?

Comment 16 Roel van de Kraats 2016-11-06 18:38:20 UTC
I'm afraid I wouldn't know how to reproduce this crash. It was indeed a one time thing (so far).

The crash happened in a (VMware Workstation) virtual machine, running on one (physical) monitor only. I'm not sure if 'guest autofit' could have a similar effect as connecting/disconnecting a monitor. As far as I remember, the screen size hadn't changed around the time of the crash though.

PS. Thanks for the quick response!

Comment 17 Fedora End Of Life 2017-07-25 23:45:48 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bug reports from releases that are no longer maintained.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 18 Fedora End Of Life 2017-08-08 19:08:13 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no longer maintained, which means that it will not receive any further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
bug.

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