I received my version of 29.3 as a regular package update for slackware 15. My system is pimped with some 32bit libraries from alienbob, another distributer of slackware packages. As a user with little to no insight in the emacs internals I would like to know, if this error message appears on other systems aswell and on other slackware systems in particular. Maybe the bug-report has to go to the slackware package maintainer?
