Comment 14 Konstantin Tokarev 2016-09-17 17:57:58 UTC
How to reproduce this crash?

Comment 15 MartinKG 2016-09-18 14:10:03 UTC
backtrace points to a problem with QtWebKit, not wit otter.
https://github.com/OtterBrowser/otter-browser/issues/1183

Comment 16 Konstantin Tokarev 2016-09-19 21:39:58 UTC
This doesn't seem to be well-known crash, we need instruction how to reproduce or at least URL where it happens in order to fix it. If this is just automatic report from abrt without any connection with user, it's safe to close this issue right away because it won't be possible to do anything about it

Comment 17 Paul Whalen 2016-09-21 16:10:01 UTC
Visiting 'https://plus.google.com/+GoogleCanada' will reproduce the crash.

Without hardware you can use qemu to reproduce https://fedoraproject.org/wiki/Architectures/AArch64/F25/Installation#Install_with_QEMU

Comment 18 Konstantin Tokarev 2016-09-21 18:49:02 UTC
Oh, I overlooked this is AArch64. In this case I'd recommended you to try building QtWebKit from https://github.com/annulen/webkit and build Otter with it.

QtWebKit that is packaged in Fedora is based on old Webkit branch that AFAIK was created before AArch64 devices were publicly available. Also, code that is crashing in your case was changed a lot, e.g. it now uses bmalloc allocator instead of custom arena with placement new, or it may be a simple bug that got fixed (I couldn't find relevant patch though) so there is a good chance that this bug is gone.

Comment 19 Fedora End Of Life 2017-11-16 15:07:38 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. 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bug reports from releases that are no longer maintained.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 '25'.

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 25 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 20 Fedora End Of Life 2017-12-12 10:11:27 UTC
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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.
