As the backtrace indicates, the crash happens not while running the Gnus code that enters the group, displaying the summary of all messages, but in the immediately subsequent redisplay. If I enter another group, the problem doesn't occur, so I guess it has to do with the current content of the summary buffer in my INBOX (i.e. probably due to some unusual email message's title). The crash happens because of: /* We should never cache on backward scans. */ if (bidi_it->scan_dir == -1) emacs_abort (); The content of bidi_it is below, in case it helps, Stefan (gdb) up #1
