Description of problem: xemacs-sumo breaks opening files while Gnus is running. Version-Release number of selected component (if applicable): xemacs-sumo 20051208-1 with xemacs-21.4.18-1.fc4 Steps to Reproduce: 1. start xemacs -f gnus 2. select Attachments->Attach File (or File->Open etc.) Actual results: xemacs prints "Window height 0 too small (after splitting)" Expected results: A file-selection window should appear (it does after terminating Gnus). Additional info: It works fine with xemacs-sumo-20050715-1. It seems .xemacs/init.el etc. is irrelevant.
Reproduced, thanks for the heads up. An updated xemacs-sumo package will be released fairly soon, but as a temporary workaround you can use the XEmacs package UI (as root) to upgrade the upstream gnus package to version 1.89; that seems to fix it for me. See http://www.xemacs.org/Documentation/packageGuide.html#Installing_automatically for more info about the XEmacs package UI.
Fixed in 20051208-2, currently in devel and soon in FE-4.
