  > @asemke, I also found problem with c3aa8b3e18d4c7be8c094a5acbd4864b09b5eb02 <https://phabricator.kde.org/R55:c3aa8b3e18d4c7be8c094a5acbd4864b09b5eb02>: If we choose octave backend, but don't write anything (so `login` don't called) and trying to open saved octave worksheet, we get segfault, because in this case we never call `OctaveSession::login` (i have checked it with `gdb`).
  
  This is fixed now with 2ca024892335728f48d7aa3dfc22032b39b10819 <https://phabricator.kde.org/R55:2ca024892335728f48d7aa3dfc22032b39b10819>. Thanks for reporting this.
