Version-Release number of selected component (if applicable): pydoc3 How reproducible: Always Steps to Reproduce: 1. Type the command 'pydoc3 -g' at the command prompt. Actual results: The command terminates with an exception thrown. Expected results: The GUI for pydoc3 starts.

This is because Fedora's tkinter and python3-tkinter were compiled without thread support. Why? Who knows? http://bugs.python.org/issue3835
My bad, I meant Tcl/Tk lacks thread support. From python.spec # Removes the "-g" option from "pydoc", for some reason; I believe # (dmalcolm 2010-01-29) that this was introduced in this change: # - fix pydoc (#68082) # in 2.2.1-12 as a response to the -g option needing TkInter installed # (Red Hat Linux 8) # Not upstream Patch1: Python-2.2.1-pydocnogui.patch Regular pydoc -g doesn't work either. It looks like their response was to remove the -g option. Hardly a fix, if you ask me. I'm going to see if I can download the src.rpm for tk and maybe tcl and enable threads.
Downloaded tcl-8.5.8-2.fc14.src.rpm Opened tcl.spec Changed --disable-threads to --enable-threads $ rpmbuild -bb tcl.spec both working now
How should I go about getting this bug fixed? Should I change the component to Tcl/Tk and request that it be built with thread support?
Moving to component tcltk because lack of thread support in Tcl/Tk is causing the problem in pydoc3.
It looks like this problem is fixed in Fedora 14.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
