Session does not close correctly on computer shutdown (while still running)

[Brandon Frohs]

Ubuntu 11.10 64bit
Nuvola Player 1.0

If Ubuntu 11.10 x64 is shut down without first closing Nuvola Player manually, the next session will bring up a dialog:

> Previous Nuvola Player session was not closed correctly.
> You can try following options to solve this issue:
> [options to reset settings]

This was not an issue prior to the change to Nuvola Player from Google Music Frame (note: this was an upgrade, will attempt a fresh install and update this issue). I've attempted clearing all settings, but I still receive the error.

TODO: fresh install

Reinstalling Nuvola Player does *not* fix the issue.

[Jiří Janoušek (fenryxo)]

Thanks for reporting the issue. The cause is that session/login manager doesn't notify Nuvola Player to quit properly, therefore the running instance is simply killed when user logs out.

> This was not an issue prior to the change to Nuvola Player from Google Music Frame
Previous series, Google Music Frame 0.x, doesn't contain crash dialog, therefore user was not notified that previous session was not closed correctly.

Note to myself: Check what signals GDM emits during log-out process or where can logout callback be registered.

[Jiří Janoušek (fenryxo)]

Fixed in trunk for GNOME and XFCE.

[Jiří Janoušek (fenryxo)]

Released in 1.0.2

Needs to be fixed in KDE (however, unlikely to be fixed by me, because I don't have enough experiences with KDE).

I also have this issue, I am running Xmonad on Fedora 16.

Infact it happens everytime I use the Xmonad quit KB shortcut.

[Jiří Janoušek (fenryxo)]

Solution independent on desktop environment could be implemented via X Session Management Protocol[1]. There is an unmaintained implementation in libegg[2][3][4]. Patches are welcome.

Since development of Nuvola Player has been discontinued [1], I'm closing the bug tracker. It will be reopened when a new maintainer is found. I'm sorry I wasn't able to address this issue.
