It also happens to me, using Archlinux and Calligra Sheets 2.8.7. It always crashes when I try to open the default template. Calligra Words works just fine. Confirmed on Arch Linux x86_64 with latest Calligra Sheets 2.9.0. Backtrace with debugging symbols from breeze: Application: Calligra Sheets (calligrasheets), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

From investigating, it looks like breeze's eventFilterScrollArea attempts to access scrollbars on QAbstractScrollArea-derived widgets, even if these scrollbars do not exist (sheets calls setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);). Interesting. The code do check for the scrollbar validity (non nullptr) few lines above the one incriminated. I guess I'll check for scrollbar policy directly.
