[Comment from a bug triager]
From bug 270933 (KDE SC 4.6.2, Words 2.4Alpha1):
-- Information about the crash:
I created a new blank document, typed some text, deleted some text, typed some
text, pressed ctrl-b. When I then started typing more text, Words crashed like
this.

Comment 2 Dario Andres 2011-04-14 12:25:56 UTC

Comment 3 Halla Rempt 2011-08-16 11:59:15 UTC

This bug is related to the changetracking. I tried to reproduce today and couldn't reproduce the exact crash, but I found two others that happen when changetracking is enabled.

Comment 4 Camilla Boemann 2012-01-29 11:21:58 UTC

Change tracking is going to be removed from 2.4 release so not a blocker

Comment 5 Myriam Schweingruber 2012-08-31 08:22:14 UTC

Is this still valid?

Comment 6 beojan 2014-06-05 12:22:04 UTC

This bug no longer appears to exist.
