Undeletable macro

[Sergei Antonov <saproj gmail com>]

Hello!
I am using mc 4.8.27 in Ubuntu.
In mcedit I recorded a macro (ctrl-r ... ctrl-r) and assigned it to
ctrl-m. Now I understand it was a bad idea, but it broke mcedit
permanently: when I try to delete or re-record a macro on ctrl-m,
mcedit sort of crashes outputting the following line infinitely.

(mcedit:18239): GLib-CRITICAL **: 16:29:22.852: g_array_remove_index:
assertion 'index_ < array->len' failed

How do I clear this macro? Removing ~/.config/mc does not help.
