If the scrollbar has a mnMin == 0 and mnMax == 0 then nVisibleSize is set to -1?! I don't know if a negative nVisibleSize makes any sense, so this just handles this case without crashing LO with a SIGFPE in the Qt library. If min == max then the visible size is just zero. It's actually not clear, that this crash is the same then the bug report, but it fixes at least the later reproducer crash.
