Ok. My Emacs suffered from a bad hair day today - two crashes in a
row. Crash #1 happened while I was marking a region, I pressed the
down arrow key repeatedly when Emacs died. Crash #2 happened after I
published my planner pages to xhtml, the output page was written
ok. Crash #1 resulted in the familiar backtrace. Crash #2 was
different but I'm afraid the backtrace is even less informative.
regards,
Markus
Crash #1
