Christian > I am sorry for inconvenience. We should definitely patch the stable version before releasing 0.2.9. Maybe we can provide for 0.2.9 and 0.3 script which will revert tasks back. There is a quick workaround how to enable your 0.2.4 tasks:
1, Open your projects.xml file located at ~/.local/share/gtg/projects.xml.
2, Edit backend element:
-> replace module="backend_localfile" by module="localfile"
-> replace attribute name path="<your path>" by filename="<your path>"
Save and GTG 0.2.4 starts correctly. (I've tried it on my own tasks, it works)
If you want to test the trunk, you should do that by these two scritps
