inkscape crashes when i try to open a particular file

[Ivan Cadri]

I've got this svg file that I was working on using inkscape on Fedora 26. It used to open without any issues and I'd edit it just fine.

However, I recently upgraded to fedora 28 and the same file doesn't open.
# uname -a
Linux localhost.localdomain 4.16.9-300.fc28.x86_64 #1 SMP Thu May 17 06:39:18 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

This is my current inkscape version
# inkscape --version
Inkscape 0.92.3 (2405546, 2018-03-11)

I've tested with Inkscape 0.92.2 (5c3e80d, 2017-08-06) as well, same result.
Attached is the file that causes the crash

# inkscape green\ tea.svg
/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.

Emergency save activated!

Seems like the offending file is in
libstdc++-devel.x86_64 8.0.1-0.20.fc28 @fedora

So I don't know whether I should be filing the bug there instead. But if I am supposed to, I don't know the context i.e. function calls etc...

Closing as a fix has been committed in 1.0alpha. I believe there's a chance an updated version of Inkscape from the Fedora repository is fixed too.

The crash is caused by numerous empty tspans in the file + the existing bugs in Inkscape.

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