Fatal error when deleting notebook

[msbentley]

When trying to delete a notebook, I wasn't clear if it had worked or not (there is no progress bar etc.) and I clicked around the UI a little. It then was clear that the note counter was decreasing. But I then received an error:

Error
Joplin encountered a fatal error and could not continue. To report the error, please copy the *entire content* of this page and post it on Joplin forum or GitHub.

I now get this on starting Joplin.

Environment

Joplin version: v1.0.226
Platform: linux
OS specifics: ubuntu 18.04

OK, Joplin did not quit cleanly and so I had to hunt down and kill it - after this, Joplin started nominally again. Feel free to close this issue if that is appropriate!

Just saw this earlier bug report.

Looks like the same one I just reported.
#3463

Just to add to this, the bug is triggered by deleting any notebook - I guess at the end of the deletion, since I didn't see this immediately yesterday, but when deleting a very small notebook today I saw this instantly.
