Does this happen every time you quit?
It seems so. I just tried this: - start calibre - press the X button on the title bar of the window => crash

still happening with calibre-2.69.0-1.fc25.x86_64
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '23'. 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 23 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.
As Filipe already commented, this still happens with calibre on fedora 25, so I'm bumping the version number.
Oh, is this the same as https://bugzilla.redhat.com/show_bug.cgi?id=1401638 ? My segfault happens with QDBusConnection in libQt5Core.so.5.7.0 .

Note that this seems to be fixed in calibre 3.0.0... but I am not ready to push that out to f25. (There is a f26 updates-testing version though).
FWIW, please see the version number on my report above :)
Odd. it no longer does this here... will try and track it down.
Have one today. calibre-2.78.0-1.fc25.x86_64 qt5-qtbase-5.7.1-16.fc25.x86_64
Have the same on fedora 26.
(In reply to Kevin Fenzi from comment #39) > Note that this seems to be fixed in calibre 3.0.0... but I am not ready to > push that out to f25. (There is a f26 updates-testing version though). No, it is not fixed in 3.0.0. Had a crash with calibre-3.0.0-2.fc26.x86_64 qt5-qtbase-5.7.1-16.fc25.x86_64 although I see calibre-3.1.1-1.fc26.x86_64 is out. (hmm, strange that I am still on qt5-base.fc25...)
Have a crash with calibre-3.1.1-1.fc26 also.

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 Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
