The problem seems to be solved now. Thanks for reminding me of my old bugs :). Closing.

Hi Julien,

claws-mail has a plugin system to add functionnality. For instance, to add PGP
support, one has to load 3 plugins from the claws-mail package. By default,
claws-mail looks in its store directory to propose available plugins.

When upgrading claws-mail, the configuration doesn't change. Plugins are still
looked for in the old store location, so old plugins are still used. This is
bad for security and compatibility. Another issue is when running guix gc
afterwards: the old plugins are deleted and claws-mail issues an error message
on startup because it cannot find them anymore.

Reading the recent activity about claws-mail, is it still an issue?

Cheers,
simon
