Able to reproduce in Fedora 28. The following is the error in the console when it happens:

/usr/include/c++/8/bits/stl_vector.h:950: std::vector<_Tp, _Alloc>::const_reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) const [with _Tp = Inkscape::Text::Layout::Character; _Alloc = std::allocator<Inkscape::Text::Layout::Character>; std::vector<_Tp, _Alloc>::const_reference = const Inkscape::Text::Layout::Character&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__builtin_expect(__n < this->size(), true)' failed.

Closing as a fix has been committed in 1.0alpha

Note version 0.92.4 in Fedora 28 and 29 (from dnf) doesn't have a crash opening this file (perhaps Fix Released is more appropriate); however, I am unsure if a commit was actually added to fix it in 0.92.x.

The commit that fixed it https://gitlab.com/inkscape/inkscape/merge_requests/488

My decision explained in the last three comments in https://bugs.launchpad.net/inkscape/+bug/1768958/ (not the most succinct)
