I messed up my topics

I messed up my topics

[Arcady Genkin]

Greetings.

I pressed some key by accident in *Group* buffer, and my topics got
really messed up.  Some of the topics do not show anymore (though the
groups are still there, which can be confirmed by switching topics
off).   The top two thirds of topics are missing (including Gnus main
topic).  If I choose to jump to a group which is not displayed, it
shows up under some other topic.

Doing `L' results in the following backtrace:
Signaling: (wrong-type-argument consp L)
  gnus-group-parameter-value(L timestamp t)
  gnus-group-get-parameter("nnimap+soup:mail/lists/freebsd/stable" timestamp t)
  gnus-group-timestamp-delta("nnimap+soup:mail/lists/freebsd/stable")
  gnus-group-highlight-line()
  run-hooks(gnus-group-highlight-line)
  apply(run-hooks gnus-group-highlight-line)
  gnus-run-hooks(gnus-group-update-hook)
  gnus-group-insert-group-line("nnimap+soup:mail/lists/freebsd/stable" 2 ((expire (9094 . 12323))) 219 "archive")
  gnus-topic-prepare-topic((("FreeBSD" visible nil nil)) 1 7 t nil 1)
  gnus-topic-prepare-topic((("Gnus" visible nil nil) (("University" visible nil nil)) (("Mail" visible nil nil)) (("Unix" visible nil nil) (...)) (("Freshmeat" invisible nil nil)) (("Linux" visible nil nil)) (("FreeBSD" visible nil nil)) (("Emacs" visible nil nil)) (("Palm" visible nil nil)) (("Fido7" invisible nil nil)) (("Stuff" invisible nil nil)) (("Saves" invisible nil nil) (...)) (("Humor" invisible nil nil)) (("Programming" invisible nil nil)) (("Blah" invisible nil nil))) 0 7 t nil 1)
  gnus-group-prepare-topics(7 t nil)
  gnus-group-list-groups(7 t)
  gnus-group-list-all-groups(nil)
  call-interactively(gnus-group-list-all-groups)

Running Gnus 5.8.8 with Xemacs 21.1.12.  I tried restarting Gnus and
Xemacs, but the problem persists.

Many thanks,

I solved the problem.  On of the nnimap groups somehow got its
parameters screwed up: it had just a character L in parameters when
checked with G p.  That's why I couldn't even unsubscribe from it.  I
just changed the parameters from `L' to `()', unsubscribed from it,
and all started working.
