Hello, please consider the following patch to vc-xemacs.el, it solves a consistent crash of Gnus after loading your new VC code. Your code uses the function 'replace-in-string' but unfortunately the 2nd argument to that function is a regexp which does not what is expected if you're trying to replace something like ?. for instance. If by chance this patch also solves http://list-archive.xemacs.org/xemacs-beta/200405/msg00355.html then please try to speed things (if you've got some time of course) to make your new VC code the default. It's a shame XEmacs is so much behind in supporting SVN. Thanks for your work, Oscar Figueiredo PS: If you want to communicate with me directly please use "oscar at cpe dot fr", oscar(a)xemacs.org gets so much spam I may miss you mail. 2005-11-1 Oscar Figueiredo <oscar(a)xemacs.org&gt; * vc-xemacs.el (subst-char-in-string): Do not use 'replace-in-string' because of the regexp semantic on its second parameter
