Target Milestone: 1.0
Since b6dfe0b33ee2a2c5c8c227b3054dfbbbb0bf0d46 was merged, occasionally (like,
once every 5 or 6 days) I end up in a situation where clicking on a grouped
task does not raise any of its windows; instead, the following is printed to
the console:
2:15:38 engine plasmashell[113060]: "Could not convert argument 0 from
undefined to QModelIndex"
Dec 06 12:15:38 engine plasmashell[113060]:

Dec 06 12:15:38 engine plasmashell[113060]:

Dec 06 12:15:38 engine plasmashell[113060]:
file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/code/tools.js:136:
TypeError: Passing incompatible arguments to C++ functions from JavaScript is
not allowed.
This is issue is difficult to reproduce, and I haven't identified the pattern
yet. Most of the time, clicking on grouped tasks works to raise the most
recently-used window.
If it helps, there are never any full-screen windows open when the issue
happens.
