Pan still crashes

Pan on F28, which I update at least once daily, still crashes instead 
of launching. From the command line with ampersand:

$ /usr/include/c++/8/bits/stl_vector.h:1021: std::vector<_Tp, 
_Alloc>::const_reference std::vector<_Tp, _Alloc>::front() const [with 
_Tp = const pan::Article*; _Alloc = std::allocator<const pan::Article*>; 
std::vector<_Tp, _Alloc>::const_reference = const pan::Article* const&]: 
Assertion '__builtin_expect(!this->empty(), true)' failed.

Alas! That is Geek to me. What should I do??
