Can't reproduce outside of the packaged version for fc28.

[Gwyn Ciesla (limburgher)]

It happens on the packaged version, compiled with:

       -DCMAKE_C_FLAGS_RELEASE:STRING="-DNDEBUG" \
        -DCMAKE_CXX_FLAGS_RELEASE:STRING="-DNDEBUG" \
        -DCMAKE_Fortran_FLAGS_RELEASE:STRING="-DNDEBUG" \
        -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \
        -DCMAKE_INSTALL_PREFIX:PATH=/usr \
        -DINCLUDE_INSTALL_DIR:PATH=/usr/include \
        -DLIB_INSTALL_DIR:PATH=/usr/lib64 \
        -DSYSCONF_INSTALL_DIR:PATH=/etc \
        -DSHARE_INSTALL_PREFIX:PATH=/usr/share \

But does not on the base tarball with:
cmake .
make -j4

I am affected, too:

inkscape --version
Inkscape 0.92.3 (2405546, 2018-03-11)

Take the exemplary drawing, select both paths and go Path → Division always yields a crash.

[Alvin Penner (apenner)]

@Bernhard - could you specify which OS?
- not reproduced on Windows 10, Inkscape 0.92.3 (2405546, 2018-03-11) using file 'drawing.svg'
- could you try running Inkscape from DOS/CLI to see if there are any exit messages?

Same with flatpak version...
