Comment 14 Jon Burgess 2015-12-20 21:53:19 UTC
Another user experienced a similar problem:

Crash likely happened the moment I logged into KDE. The K-gears appear for about 30 seconds, fade to black and then nothing. I have to manually kill and start  a new plasmashell instance to get anything useful on the desktop.

Comment 15 Jan Kurik 2016-02-24 14:00:22 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

*** Bug 1317033 has been marked as a duplicate of this bug. ***

Comment 17 Rex Dieter 2016-03-11 18:57:11 UTC
this crash line reference is a qWarning 

"The X11 connection broke (error_code), Did the X11 server die?"

which is wrapped under

int connection_error = xcb_connection_has_error(xcb_connection());
if (connection_error)
  qWarning(...)
  exit(1);
}

So... wierd?

Comment 18 Jon Burgess 2016-03-11 23:28:31 UTC
The backtrace looks quite different to the abrt trace:

Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x00007f58640a9731 in QSqlDatabase::close (this=this@entry=0x55c00b82f688) at kernel/qsqldatabase.cpp:871
871	    d->driver->close();
...
#10 0x00007f5878dea1a5 in __GI_exit (status=status@entry=1) at exit.c:104
No locals.
#11 0x00007f5868f3470e in QXcbConnection::processXcbEvents (this=0x55c00b5875a0) at qxcbconnection.cpp:1470
        connection_error = <optimized out>
        eventqueue = <optimized out>

This looks similar to the report below where a crash happened during exit():

Comment 20 Fedora End Of Life 2017-07-25 19:32:24 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bug reports from releases that are no longer maintained.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 21 Fedora End Of Life 2017-08-08 12:26:47 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.
