Воспроизведение (на примере пакета/репозитория rpm):
1) создайте новый проект, выберите импорт существующего проекта, выберите директорию репозитория
2) в терминале в директории репозитория: autoreconv -fisv
3) ./configure --prefix=/usr --libdir=/usr/lib64 --with-vendor=alt --with-external-db
4) find . -type d | sort | grep -v '.git' | sed -e 's|^\./||g' > имя_проекта.includes
5) find . -name '*.c' -o -name '*.h' > имя_проекта.files
6) переключиться обратно на qt-creator

qt-creator падает.
