emacspeak and emacs 22 GTK bug?

[Tim Cross <tcross@xxxxxxxxxxx>]

Hi Raman,

I think you misunderstood me. I don't want you to grab a pre-built version. I
wanted to ask if you wouldn't mind checking the describe function information
with the version you have already built from CVS. I'm already working with the
package maintainer to see if the problem lies there. 

The issue I'm encountering is subtle and is only revealed iff you have
extra advice defined for view-file other than emacspeak. Just running emacspeak
without any non-emacspeak advice defined does not reveal the problem and
therefore would not necessarily show up in a simple test. 

All I wanted was some confirmation that the describe-function operation run on
view-file in your CVS version of GTK emacs is correctly reporting that the
function has been advised. The version I am running is not
reporting this correctly on my system and I wanted to verify that yours is
correct as this would indicate I have some other issue on my system not related
to the CVS sources or the packaged version. 

To summerise 

 - After starting emacs 22 GTK version and loading emacspeak, do a C-h f
   view-file. Scroll to the bottom of the output where it should say "This
   function is advised etc". If it does not, try an apropos on view-file and
   see if you have an entry for ad-Orig-view-file. Note that at this point,
   view-file appears to work perfectly fine. If you do see this inconsistency,
   you will then find if you load my txutils.el utility and repeat the process,
   both the emacspeak and txutils advice are reported, but now view-file is
   broken and will generate a backtrace if debug on error is enabled.

If you can do this check, it would be appreciated. If you can't, then don't
worry. I will have my download quota renewed in a couple of weeks and will grab
a fresh copy of the CVS and build my self to check. 

BTW Note that none of this inconsistency in reporting of advice or any of the other
issues exist in the non-GTK version, which is built from exactly the same
sources.

There are two types of people in IT - those who do not manage what they 
understand and those who do not understand what they manage.
