[Bug 58856] Re: xemacs segfaults on edgy powerpc system
well, this bug is not confined to powerpc systems, and it still exists on all machines that are upgraded from breezy to edgy. Please confirm this bug and push it out to the X11 maintainers so they can check for the condition of an upgrade and do something intelligent about the font paths in the xorg.conf file.

[Bug 58856] Re: xemacs segfaults on edgy powerpc system
Okay... I have a functional workaround for this bug, but the segfault itself should still be pushed upstream so that the xemacs devs can fix it. The application is choking when it can't populate a font struct during initialisation; I guess they never try to clean up for this condition, which is causing the app to throw a segmentation fault... anyhow, on ubuntu the reason this is happening is that when you have a machine that has been carried forward from an older version of ubuntu (dapper, or breezy), the xorg.conf will have bad loadpath lines for fonts. Before and after clauses from my xorg.conf: #Section "Files" # FontPath"/usr/share/X11/fonts/misc" # FontPath"/usr/share/X11/fonts/cyrillic" # FontPath"/usr/share/X11/fonts/100dpi/:unscaled" # FontPath"/usr/share/X11/fonts/75dpi/:unscaled" # FontPath"/usr/share/X11/fonts/Type1" # FontPath"/usr/share/X11/fonts/100dpi" # FontPath"/usr/share/X11/fonts/75dpi" # # path to defoma fonts # FontPath"/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType" # FontPath"/var/lib/defoma/x-ttcidfont-conf.d/dirs/CID" #EndSection Section "Files" # paths to defoma fonts FontPath "/usr/share/fonts/X11/misc" FontPath "/usr/share/fonts/X11/cyrillic" FontPath "/usr/share/fonts/X11/100dpi/:unscaled" FontPath "/usr/share/fonts/X11/75dpi/:unscaled" FontPath "/usr/share/fonts/X11/Type1" FontPath "/usr/share/fonts/X11/CID" FontPath "/usr/share/fonts/X11/100dpi" FontPath "/usr/share/fonts/X11/75dpi" FontPath "/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType" FontPath "/var/lib/defoma/x-ttcidfont-conf.d/dirs/CID" EndSection ... the faulty fontpath clause is commented out. The new one is below it. Once this change was made to my xorg.conf and the server was restarted, XEmacs and GNUEmacs both worked again as advertised. The fact that this exposes a segfault in xemacs is a bug for upstream in my oppinion. This should be something that is checked for when doing a dist-upgrade from breezy or dapper.

this appears to duplicate the bug at: https://launchpad.net/distros/ubuntu/+source/xemacs21/+bug/57586 ... although the traces there aren't complete. I think these two reports should be merged, and probably the bug marked as verified.
