Flood fill anywhere crashes Inkscape

[Johan Rosenkilde]

Inkscape 0.92.3 on Fedora 28

1. Open Inkscape

2. Draw any shape

3. Select Flood fill tool

4. Flood fill in the drawn shape

5. Crash:

/usr/include/c++/8/bits/stl_deque.h:1463: std::deque<_Tp, _Alloc>::reference std::deque<_Tp, _Alloc>::front() [with _Tp = Geom::Point; _Alloc = std::allocator<Geom::Point>; std::deque<_Tp, _Alloc>::reference = Geom::Point&]: Assertion '__builtin_expect(!this->empty(), true)' failed.

Emergency save activated!

Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.

Additional info:
- The bug also appeared on Fedora 27 with the version of Inkscape there. I didn't record which one, sorry.
- I'm using Adwaita theme, but the bug also happens with Raleigh (cf bug #1365355).
- I've tried to remove ~/.config/inkscape but the bug remains with the clean user config.
- I currently don't know any workaround that lets me use Flood fill.

Why is this bug filed against gtk2-engines-oxygen if it also reproduces with Raleigh?

[Johan Rosenkilde (jsrn)]

Because I apparently got lost in Launchpad. I meant to file this with Inkscape. Sorry for the noise.

I finally got around to compiling Inkscape myself, and I can confirm that this happens on the Fedora packaged version of Inkscape, but not with the one compiled simply with "cmake ..; make".
