--- Comment #2 from RJVB <rjvber...@gmail.com> ---
Backtrace below.
Among the things I tried was not deleting only attributes of type
NoteDisplayAttribute. That actually made things worse, somehow, causing crashes
even when the application was starting up.
I do wonder about the delete, which appears to be a recent addition.
QHash::insert doesn't make copies as far as I read its documentation, so why
the delete? To allow the code registering an attribute to forget about it?
Maybe libnoteshared registers attributes it then deletes itself?
