Full backtrace

SUMMARY
On my system, Calligra words from Manjaro packages and compiled from source crashes when saving (manual or autosave).

The backtrace tells the crash happens when creating the thumbnail of the odf file, or in a posterior step, probably while interacting with libfreeimage.

Backtrace (full backtrace attached):
