Hi,

please report this directly to the bugtracker:

https://github.com/owncloud/core/issues

Am I better off not re-installing?

I'm trying to use this install in a professional office...

I don't think that a reinstall will solve this. That repair step can't load a specific class however according to your posted integrity status:

No errors have been found.

you have no broken / missing files. So this looks to me like a bug in 9.1.0 itself which won't be solved by reinstalling.

Thanks
I'll close this as I've now opened issue on own cloud/core
