It's unlikely to be a package directly causing it, but it may be doing something which causes a bug in Emacs itself to show. > Is the standard disable each package one by one and see if it can be > narrowed down to a single package the way to go forward now? The usual way would be a binary search type strategy. Comment out half your config, then see if you still have the problem, if not try the other half. Then you half what remains, and repeat until you've found the cause. The problem is that it may be a combination of things that are causing it, but at least it may give us a chance to get a minimal recipe to replicate the bug. -- Alan Third
