This seems to happen especially when running JDownloader 2 BETA in another workspace (not the currently active one)
I'm seeing this more often… It seems like I'm running into this bug under some conditions when JDownloader 2 BETA (a Java Swing application with some custom theming and custom dialogs/windows) is running. It happens with JDownloader having focus, with JDownloader being in background and with JDownloader being on a different workspace. It only happens when switching to applications overview. Every time when switching from any application to overview with JDownloader running there is about 10% chance to run into this bug. This bug seems to be unrelated to specific versions of JDownloader (I'm running into this bug for some time). I'm not running into this bug when using Alt+Tab. It does not seem to matter whether I use the super key or the mouse to enter activities view.
I hunted it down to happen only with some Java Swing applications and gnome shell extension "WindowOverlay Icons" enabled. According to ABRT this bug is at least related with https://bugzilla.redhat.com/show_bug.cgi?id=995785 and thus https://bugzilla.gnome.org/show_bug.cgi?id=711618 I noticed that sometimes the Java application has focus (input focus) but is not active (use extension "shade inactive windows") or keeps being in background after switching via Alt+Tab or Activities overview. I tested some Java applications: JDownloader 2 Beta, Mediathek View, JOSM: crashed Minecraft (both barely using Swing): no crash JDiskReport, pdfsam: no crash Eclipse (using SWT, no Swing): no crash
I hit it too, i have the window overlay icons extensions, but i'm not running any java applications.
I'm seeing this now without any java applications running, too.
Another user experienced a similar problem: I just tried to enter the overview mode from JDownloader. reporter: libreport-2.1.11 backtrace_rating: 4 cmdline: /usr/bin/gnome-shell crash_function: _g_log_abort executable: /usr/bin/gnome-shell kernel: 3.12.8-300.fc20.x86_64 package: gnome-shell-3.10.3-1.fc20 reason: gnome-shell killed by SIGABRT runlevel: N 5 type: CCpp uid: 1000
I only experience this problem when I activated the plugin "WindowOverlay Icons". I guess the problem is related to this plugin.
I see this too a lot with Office 2007 in Wine, sometimes after unlocking the shield and sometimes just randomly. I'll see if disabling the overlay extension helps like you say.
I've disabled the WindowOverlay Icons extension among some others and the crashes indeed went away. However, after a few weeks I re-enabled most or all of them (including the mentioned culprit) but the issue hasn't returned so I'm not sure what the real problem is.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. 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 '20'. 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 20 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.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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.
