From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.5) Gecko/20041110 Firefox/1.0 Description of problem: When running emacs in an X window under Fedora Core 3, it frequently crashes with the message: X protocol error: BadWindow (invalid Window parameter) on protocol request 25 ... or something similar. This is not limited to the local machine only; for example, if I ssh into a machine running Fedora Core 2 and run emacs, it has the same behaviour. (Obviously, if I disable X forwarding and/or use the -nw option, this doesn't happen, but then emacs is crippled.) Version-Release number of selected component (if applicable): xorg-x11-6.8.1-12.FC3.1 How reproducible: Sometimes Steps to Reproduce: 1. Run emacs in an X window on a stock Fedora Core 3 system. 2. Do a bunch of editing. 3. Actual Results: Sooner or later, it will crash. This applies even if it is an emacs from another machine. Additional info:
This is covered in the Fedora Core 3 release notes.
