Segmentation fault BSE with Slepc in calculation restart

If I run again a BSE calculation on a folder where the calculation finished with success, without changing the input, I get this segmentation fault

If I erase the database ndb.BS_diago_Q1 and I start it again it works. The bug is easy to reproduce, I will have a look
