ebrowse completion broken in emacs 21.2

ebrowse completion broken in emacs 21.2

[Stephen Crowley]

Does ebrowse completion work for anyone in emacs 21.2? I'm using the 
debian package emacs21-21.2-5.

I generate the BROWSE file using 'ebrowse *.cpp', and I can browse it 
just fine when going into ebrowse mode, however the completion function, 
ebrowse-tags-complete-symbol is broken and I get the following error 
when trying to use it.

Invalid function: #<hash-table 'equal nil 90/97 0x857a1b0>

I saw something about this on some mailing lists months ago, but there 
was no solution. Is this a known bug, or something I am doing wrong?

Looks like you're using an ebrwose.el more recent than the one that should
come with Emacs-21.2.

I am using whatever came with emacs21, what other problem could it be?

Try it with `emacs -q --no-site-file' also try:

  M-x list-load-path-shadows RET

as well as (after loading ebrowse):

  C-h f ebrowse-copy-list RET

and tell us what comes out.

I just can't bring myself to believe that it can be caused
by something else.  Of course, it might be a problem with Debian's
Emacs package, although that sounds unlikely.

Doesn't work with this either.

ebrowse-copy-list is a compiled Lisp function in `ebrowse'.
(ebrowse-copy-list LIST)

Return a shallow copy of LIST.

It might be possible.. I'll check into it. A quick search of the BTS 
doesn't reveal anything however.

So it looks like you have the "old" ebrowse.el alright.  Damn!
Well, then: select `Option => Enter Debugger on Error' in the menu,
reproduce the error, and send us the backtrace.

Here is the backtrace:

Debugger entered--Lisp error: (invalid-function #<hash-table 'equal nil 
91/97 0x86f0de8>)

Hmmm... I can't seem to find where this problem was introduced.
Have you ever gotten this functionality to work before
(e.g. in Emacs-21.1) ?

I'm not sure if i worked in 21.2, I guess I could try installing it and 
see if the problem persists... I'll check it out when I get time.
Thanks for the help.
