Comment 8 Raphael Groner 2018-04-21 15:51:37 UTC
Thanks for the report. Can you reproduce the issue? What did you do?

The provided backtrace indicates some issue with automount. Maybe the backup device got removed too early, so backintime did not get a chance to finish properly its job.

You may want to try our copr build with a git snapshot for Qt5, please let us now if the issue is reproducible:

Comment 9 Martin Ueding 2018-06-06 17:48:00 UTC
I believe that this has not occurred any more, so I'll just close this.
