I get frequent crashes (2-3 times an hour) of the plasma desktop shell when
using apps like Akregator and Thunderbird. There seems to be a bug in the
QDeclarativeRepeater function when removing items from the list of
notifications.

The bug was reported upstream at https://bugs.kde.org/show_bug.cgi?id=311871.
I am hoping for a quick fix once the problem is solved, please don't wait for
4.10.1...

See the crash log below:
