This was fixed in 3.30.1 with the following commit:
commit 1123fc250b70406b0bac7df48454bcf8a7fccb98

updates section: Fix a crash during automatic updates
When self->list is cleared, a bunch of variables pointing to items
constructed in _build_section_header() become invalid. Make sure that we
set those to NULL when self->list is cleared so that we can avoid using
dangling pointers in callbacks.
