Description phelps.sg 2017-11-29 14:04:21 UTC
Description of problem:

Gnome-shell is highly unstable when extensions are installed are enabled.

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1.  Install a random selection of approximately 12 shell extensions
2.  Enable shell extensions
3.  Watch as gnome-shell crashes and burns

Actual results:

With extensions installed, gnome-shell SEGVs often and/or the shell becomes laggy.  Only a small subset of the available third-party extensions work well with any given version of the gnome shell.  Upgrading Fedora distros typically entails disabling all shell extensions, and then re-enabling them one by one in order to find out which ones work with the newly-installed distro.

Expected results:

If extensions are offered to the user as a feature of the shell, then the shell should still be usable even when a given extension is ill behaved.  The design of the shell should provide robust compartmentalisation from ill-behaved extensions.  Analogously,  if a single process is ill behaved, the kernel should continue to run.

This message is a reminder that Fedora 27 is nearing its end of life.
On 2018-Nov-30  Fedora will stop maintaining and issuing updates for
Fedora 27. 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that are no longer maintained.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 '27'.

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 27 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 4 Ben Cotton 2018-11-30 22:03:56 UTC
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 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no longer maintained, which means that it will not receive any further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.
