Since a recent update in Arch Linux to gtk3/clutter/cogl, parole (built from git) segfaults when the clutter backend is enabled. Not using the "--enable-clutter" configuration parameter makes parole work again. This is probably related to clutter migration to gdk backend (from x11)- see: https://blogs.gnome.org/clutter/

seen with 0.8.0-2ubuntu1 and 0.8.0+git-0~898~ubuntu15.10.1

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Paul White (paulw2u)]

Additional problem - can't seem to close parole using either the close button or from the menu.

[Ubuntu QA Website (ubuntuqa)]

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:
http://iso.qa.ubuntu.com/qatracker/reports/bugs/1462445

[Paul White (paulw2u)]

For what it's worth, parole *does* start and works as it should in an Ubuntu live session using daily build 20150606.

@Alberto - Low?

When we've marked the upstream one Medium?

If you're not sure how Xubuntu wants bugs marked - could you either ask or leave them alone. Thanks

[Jackson Doak (noskcaj)]

IMO this should be medium at least, since it fits the guideline of "A usability issue that does not limit the functionality of a core application" given files cannot be opened from parole, but have to be opened via the file manager.

Just checking, the inability to play/pause and skip is also from this bug?

[Simon Steinbeiß (ochosi)]

*** Bug 11965 has been marked as a duplicate of this bug. ***

[Simon Steinbeiß (ochosi)]

Just so everybody is on the same page: this is a bug in clutter, even totem doesn't start in 15.10. We can relink the bugreport against clutter, when we have found some upstream report that reflects this problem.

[Jackson Doak (noskcaj)]

Reverting to the old backends fixes this, see https://bugzilla.gnome.org/show_bug.cgi?id=743085

[ToZ (toz)]

Updates to clutter (1.22.4-1) and clutter-gtk (1.6.2-1) have not fixed the issue for me. Also, I don't have an nvidia card but an Intel one. I'm currently building parole without the --enable-clutter parameter for it to work.

Forcing the x11 clutter backend via "CLUTTER_BACKEND=x11 parole" does not work either.

[Simon Steinbeiß (ochosi)]

@Toz: What Jackson meant was switching to either the X11 or XV backend in Parole, not clutter itself.

You can do this for instance from the command line (or xfce4-settings-editor):
xfconf-query -c parole -p /video/videosink -s "xv"

[Simon Steinbeiß (ochosi)]

We have meanwhile uploaded a workaround to 15.10 in xubuntu-default-settings 15.10.1: http://bazaar.launchpad.net/~xubuntu-dev/xubuntu-default-settings/trunk/revision/576

[Jackson Doak (noskcaj)]

Reverting clutter's backend change will also fix this issue, at least for me

[Sean Davis (bluesabre)]

Added Mugshot as affected project. The next release uses a clutter/Cheese based backend to render the webcam video. It works correctly in vivid, but fails in wily in the same way parole is affected.

Launching mugshot with: CLUTTER_BACKEND=x11 resolves the issue.

Relevant library versions:
gir1.2-clutter-1.0:amd64 (1.22.4-1)
gir1.2-gtkclutter-1.0:amd64 (1.6.2-1)

[Sean Davis (bluesabre)]

Previously associated bug was resolved but did the fix did not apply to these applications. Created a new upstream bug.

[Launchpad Janitor (janitor)]

This bug was fixed in the package xubuntu-default-settings - 15.10.3

---------------
xubuntu-default-settings (15.10.3) wily; urgency=medium

  * etc/X11/Xsession.d/56xubuntu-session
    - Workaround clutter freezing gtk applications (LP: #1462445)
  * etc/xdg/xdg-xubuntu/xfce4/xfconf/xfce-perchannel-xml/parole.xml
    - Set parole video sink back to clutter
