Speedbarv0.13: "e" fails in "speedbar-tag-find" & mouse-clicks ignored

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.4 (patch 3) "Academic Rigor" [Lucid] (i686-pc-linux) of Tue Jul 10 2001 on eos.redmond.cacheflow.com configured using `configure --prefix=/home/david.karr/local' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I have two separate issues with Speedbar, v0.13 and v0.13a (from sourceforge). After opening up Speedbar and seeing the file list, and opening up the functions in a file, I put the cursor on one of the functions and typed "e", and got the following stack trace: Signaling: (wrong-type-argument integer-or-marker-p #<extent [8017, 8261) semantic 0x88b2084 in buffer XMLplugin.c>) speedbar-tag-find("XMLdestroy()" #<extent [8017, 8261) semantic 0x88b2084 in buffer XMLplugin.c> 3) speedbar-do-function-pointer() #<compiled-function nil "...(24)" [0 re-search-forward "[]>?}] [^ ]" nil t speedbar-do-function-pointer] 4 ("/home/david.karr/speedbar/speedbar-0.13a/speedbar.elc" . 75908) nil>() call-interactively(speedbar-edit-line) dispatch-event(#<keypress-event e>) dframe-xemacs-popup-kludge(#<buttondown-event button3>) call-interactively(dframe-xemacs-popup-kludge) The other more minor issue is that when I click on the "+", for either files or sections of files, it does nothing. Typing "+" works, but not the mouse. I'm using the version of Semantic that's installed with XEmacs 21.4.3, which appears to be 1.3.3.
