Its frequency is also not very predictable and is hard sometimes to
reproduce the error.

hh4name --- // in the error description

Is calculated through indexed-repeat, and i just noticed that if i try to
delete a group somewhere in the middle it causes the crash, if it is most
recent/last position, it lets me to delete without any problems.
