[bug report] error with gnus-thread-hide-subtree

[Ralf Wachinger]

Hi,

I have tried the following example from the gnus manual out

,----[ info "(gnus)More Threading" ]
|
| (setq gnus-thread-hide-subtree
|       '(or gnus-article-unread-p
|            gnus-article-unseen-p))
`----

Then the following error occurs:

,----[ backtrace ]
|
| Debugger entered--Lisp error: (invalid-function (macro . #[(&optional number)
| "... unrepresentable characters ..."
| [number gnus-data-header gnus-data-find (gnus-summary-article-number)] 3 (".../gnus-sum.elc" . 107727)]))
|   gnus-summary-article-header(5023)
|   mapcar(gnus-summary-article-header (5023 5024 5025))
|   gnus-map-articles((lambda (elem) (or (gnus-article-unread-p elem) (gnus-article-unseen-p elem))) (5023 5024 5025))
|   gnus-summary-hide-all-threads((lambda (elem) (or (gnus-article-unread-p elem) (gnus-article-unseen-p elem))))
|   gnus-summary-maybe-hide-threads()
|   gnus-summary-read-group-1("de.comm.software.newsreader" nil t nil nil nil)
|   gnus-summary-read-group("de.comm.software.newsreader" nil t nil nil nil nil)
|   gnus-group-read-group(nil t)
|   gnus-group-select-group(nil)
|   gnus-topic-select-group(nil)
|   call-interactively(gnus-topic-select-group)

where a similar error is reported.

The error occurs no matter which group, or if there are unread articles
in a group or not, or how many articles I select for display in the
summary buffer.

I use: Gnus/5.11 (Gnus v5.11) Emacs/22.0.50 (windows-nt)

It happens because of calling a symbol macro.  I've fixed it in
the trunk and the v5-10 branch.  Thank you for the report.
