persist/activities-activities can disappear during development

[jdtsmith]

I have noticed that (rarely) the persist file persist/activities-activities has gone missing a couple of times during development (of #83). It's possible this variable was somehow set to nil, and auto-save with persist deletes the file if this occurs, but I don't have a reasonable explanation for that. I wanted to open this in case others have experienced this.

One remedy might be to make the default value for that variable 'unspecified or similar, that way it's unlikely for the variable's value to match, and for persist to remove the file.

Sorry, I was unclear. I think this issue should be discussed with the persist maintainer. It doesn't seem to have a repo outside of ELPA.git itself, so I guess we should discuss it on emacs-devel and/or file an Emacs bug report. I'd rather not deal with it on this repo, since it's not really about activities.

Understood, will keep an eye open for further instances (and keep a backup of my persist file handy).
