Task filter by label ineffective

[Fabian Stanke]

Zim 0.67 on Windows

The Task List plugin provides a configuration to "Consider all checkboxes as tasks" (checkbox) and a setting for "Labels marking tasks" (text field), which defaults to "FIXME, TODO".

Expected behaviour and actual behaviour until version 0.65 is that when the checkbox is unchecked, only tasks preceeded by one of the labels (either on the same line or on the line above) are included in the task list.

Since version 0.66 and also in present version 0.67 (on Windows) this filter does not work any longer. Irrespective of the checkbox setting, all checkboxes in the entire notebook are considered as tasks and displayed in the task list.

Please restore the behaviour of version 0.65.

In my case, the notebook has more than 5000 checkboxes, but (hopefully) only a fraction of those are tasks. I can work around the bug by appending an additional @ label to all actual tasks. The problem is that apparently all checkboxes seem to be indexed for the task list: if the task list is displayed, Zim freezes for about 5 seconds every time I save a page and on autosave, significantly degrading the user experience. Thus I'm forced to keep the task list closed at all times, which is hardly the point of a task list ...

The problem can be reproduced with a new notebook with the following Home.txt. When opening the task list, two items ("No task" and "task") are listed, irrespective of the state of the "Consider all checkboxes as tasks" checkbox in the Task List settings.
