Proposed as a Blocker for 24-final by Fedora user me2 using the blocker tracking app because:
I propose this bug as final blocker. It clearly violates the final criterion:
"Default application functionality
All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully and withstand a basic functionality test."
Calligra is installed by default on KDE from liveCD.
Found an upstream report already, that seems to match the symptoms and backtrace,
The upstream reports seem to point to this being a soprano issue, where it cannot find any backend plugins.
Unfortunately, our soprano packaging includes at least one default backend: redland.
Already had to patch soprano for some gcc6'isms, I suspect something else isn't working right.
Simply rebuilding soprano seems to fix it for me (old gcc/toolchain bug?) I'll whip up some new soprano builds for testing.
