bug#541: Trouble getting archive files to load

[Davin Pearson]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Running Emacs with -Q and -q and executing the following code:

(add-to-list 'auto-mode-alist
'("\\.\\(arc\\|zip\\|tar\\|gz\\|lzh\\|zoo\\)\\'" . archive-mode))

gives the following error when I try to load a *.tar or *.tar.gz file:

File mode specification error: (error "Buffer format not recognized")

It works fine loading *.zip files however.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
d:/Program Files/emacs-22.2/etc/DEBUG for instructions.
