Steps to reproduce: I expect you'll need the 4.9MB file I was using. I uploaded it here for debugging purposes: http://streetgreek.com/files/bhs.txt I tried the following with non-bidi-Hebrew containing file and couldn't reproduce the bug. using an emacs bzr pull from today: ------------- $ emacs -Q /path/to/file/bhs.txt ------------- at this point I already get this error in the Gnome Terminal window from which I called Emacs (this comes even if I only run 'emacs -Q')ema: ** (emacs:22720): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed [now I move around file using PgUp/PgDn, M-S->/< and point moving commands Sample dribble log attached to this message] Emacs crashes with either: Fatal error (11)Segmentation fault or: Fatal error (6)Aborted The actual moment of the crash comes with various commands. Once it was C-x 3, once it was M-<, once it was a PgUp. It was always after dozens of movement commands. Never right away. (Hence the length of the attached dribble log) The file is a 4.9MB text file in UTF-8 with both Hebrew and English text. Note that the final lines of the file set the buffer local variable 'bidi-display-reordering' to 't', since I was testing bidi display. This is the output of 'locale' on my system: LANG=en_GB.utf8 LC_CTYPE="en_GB.utf8" LC_NUMERIC="en_GB.utf8" LC_TIME="en_GB.utf8" LC_COLLATE="en_GB.utf8" LC_MONETARY="en_GB.utf8" LC_MESSAGES="en_GB.utf8" LC_PAPER="en_GB.utf8" LC_NAME="en_GB.utf8" LC_ADDRESS="en_GB.utf8" LC_TELEPHONE="en_GB.utf8" LC_MEASUREMENT="en_GB.utf8" LC_IDENTIFICATION="en_GB.utf8" LC_ALL= The system is Ubuntu 10.4 running Gnome. I'll give more info if required.
