[Bug-AUCTeX] 11.81; 11.81 lock-up

[Jan-Ake Larsson]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  If the bug (or problem) is triggered by a specific
(La)TeX file, you should try to produce a minimal sample file
showing the problem and include it in your report.

Your bug report will be posted to the AUCTeX bug reporting list.

When editing a large(ish) file, pressing C-k on a row with a preview
(?) caused a lockup. Pressing C-g will return the cursor. This has
occurred in several files. After 'quit any command will cause a
lockup. Luck that C-x C-s saves before the lockup occurs. Reloading
the file into the same buffer resets. Shortened backtrace:

Debugger entered--Lisp error: (quit)
  preview-canonical-spaces("....")
  mapcar(preview-canonical-spaces ("...." "$\\pact i$"))
  preview-relaxed-string=("...." "$\\pact i$")
  byte-code("..." [text ov extent-object buffer-substring-no-properties

  preview-move-point()
