Bug Description

Binary package hint: gtg


Pressing the "delete" key when no task is highlighted has the unexpected behavior of creating a new task.


1. Open the main tasks window.
2. With no task highlighted, press the "delete" key.
3. An window will open with the "Are you sure you want to delete this task?" dialog, for a task called "- My New Task". At the same time, a task called My New Task will be created in the main tasks window (visible behind the dialog).
4. Click on either option or hit enter. It doesn't matter. The new task is still there.


Pressing delete with no task highlighted will have no effect,
AND POSSIBLY after you have deleted one task, the next one in line will be highlighted.

I don't get the same behavior as described above with rev 821, instead I get a traceback.

get_task should take a tid

Yep, this is reproducible on current trunk. Here's the backtrace I got:

Jeff, thank you for the patch, I've committed it to bzr trunk as revision 862. It will be included in the 0.3 gtg release.

Since the bug does not appear to cause the program to exit or result in any data loss, it probably is not going to qualify for a SRU for Ubuntu Lucid. But hopefully 0.3 will be included in Ubuntu Maverick.
