God damn it. I don't know if you remember my post from yesterday where I was
talking which hooks to attach `minibuffer-line--update' to in order to update
minibuffer line on window and buffer switches properly. The conclusion was
(add-hook 'buffer-list-update-hook #'minibuffer-line--update)
(add-hook 'window-configuration-change-hook #'minibuffer-line--update)
By examining the GDB output (which obviously repeats):
#1084 0x00000004001f0978 in run_hook_with_args (nargs=1, args=0x7a8d40,
funcall=0x4001f0434 <funcall_nil>) at

I've somehow recalled those hooks. It turns out that this one
(add-hook 'buffer-list-update-hook #'minibuffer-line--update)
is seems to be causing the infinite recursion and most importantly only in the
case of `M-x gnus RET' as I haven't experienced that before.
Yes, the recursion is clearly visible in the Lisp backtrace.
What could be the problem here, Eli?
I think this part of the Lisp backtrace should give you a clue:
"format-time-string" (0x8318d0)
"propertize" (0x831b18)
"let*" (0x831d68)
"eval" (0x831fc8)
"format-mode-line" (0x833810)
"minibuffer-line--update" (0x833e88)
"run-hooks" (0x833fc8)
"format-time-string" (0x8356a0)
"propertize" (0x8358e8)
"let*" (0x835b38)
"eval" (0x835d98)
"format-mode-line" (0x8375e0)
"minibuffer-line--update" (0x837c58)
"run-hooks" (0x837d98)
"utf-7-imap-post-read-conversion" (0x839ce8)
"decode-coding-string" (0x83a380)
"utf7-decode" (0x83a8d0)
"nnimap-get-groups" (0x83ae40)
"nnimap-request-newgroups" (0x83b3b0)
"gnus-request-newgroups" (0x83b920)
"gnus-ask-server-for-new-groups" (0x83be90)
Somehow, minibuffer-line--update calls format-mode-line, which calls
format-time-string, which again calls run-hooks, which again calls
minibuffer-line--update. Look into your hook and see how this can
happen.
