cl-no-applicable-method clone nil error when fetching MRs

[Davidbrcz]

Hello

I recently started getting the following error when trying to fetch MRs from the gitlab instance I'm working with when I hit ' f f. Everything used to work flawlessly, but now the list of topics is not displayed.

Love the work and the efforts, thank you so much for magit.

I am still getting the same error with the latest master. forge--buffer-topics-spec seems to be nil. It does not happen the first time I install Forge. However, as soon as I close and reopen emacs it results in this same issue. I can confirm this happened with the following command:

Check the value of magit-status-mode-hook. Is forge--init-buffer-topics-spec a member of that list?

[tpeacock19]

the value is:

(forge--init-buffer-topics-spec
 forge-connect-database-once
 arx-magit-remember-project)

However, I have now realized that this happens most commonly when I restore my the magit status window from a bookmark (using @alphapapa's activies.el but still leveraging the built-in bookmark functionality) in a brand new instance of emacs. When I kill all of the magit buffers and re-execute magit-status, then it works as expected.

Perhaps it has something to do with the magit bookmark support not initializing the forge spec variable?

[tpeacock19]

Apologies, you can ignore this. It turns out I wasn't loading Forge until after the first magit-status call. Sorry for the noise.
