If you insert a textbox in LibreOffice writer and try to use a subscript via either Ctrl + Shift + B or a button, LibreOffice Writer will crash and immediately close. As a temporary workaround, I have found that I can write out the string, including subscript and then copy--> paste it into a new text box without issue. To reproduce: 1. Start up LibreOffice Writer 2. Make a new text box: Insert --> Text box 3. Click the "subscript" formatting button or use Ctrl + Shift + B At #3 Writer will crash.
As an addition, here is a back trace for the bug: Application: soffice (soffice), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
