Bug Description
GNOME Tweak Tool crashes when enabling the 'Activities configurator' extension in Ubuntu GNOME 13.10, using GNOME 3.10.1, installed from the following PPAs:
- https:/
- https:/
This problem is probably caused as a result of the bug #1236749 . After every reboot all pre-enabled GNOME Shell extensions are disabled, so one must enable them manually at every startup (if not using the workarounds).
Having installed a number of extensions including the 'Activities Configurator', every time I try to enable the installed extensions after a reboot using gnome-tweak-tool, it crashes when I turn the 'Activities Configurator' ON. This doesn't happen with any other extention, but the Activities Configurator. The 'Activities Configurator' turns ON normally as it should, but gnome-tweak-tool crashes instantly afterwards.
The strange thing is that the crash occurs only the first time I try to enable this extension. After gnome-tweak-tool crashes I launch it again and turn the 'Activities Configurator' ON & OFF (enabling/disabling multiple times) and gnome-tweak-tool doesn't crash, but works as it supposed to.
How to reproduce:
1) In Ubuntu GNOME add the above PPAs to the Software Sources.
2) Update and upgrade using: sudo apt-get update && sudo apt-get dist-upgrade
3) After rebooting install the Activities Configurator extension from https:/
4) Reboot - The extension(s) now should be disabled because of bug #1236749.
5) Launch gnome-tweak-tool and turn on the 'Activities Configurator' extension.
What happens:
1) The extension turns ON, as it should.
2) gnome-tweak-tool crashes (that's the problem)
What should happen:
1) gnome-tweak-tool should stay open and functional after enabling the extension.
I repeat that this happens only the first time that I enable the extension after a reboot. If I disable it and re-enable it during the same session, gnome-tweak-tool won't crash.
The information collected by apport are attached to the report.
Thanks.
