Regression in wine 0.9.6 in riched20 causes program to fail

[Arren Lex]

Wine suffered a regression between 06:47:19 CST (12:47:19 UTC) and 06:47:20
CST (12:47:20 UTC). CVS indicates that the files
P wine/dlls/riched20/caret.c
P wine/dlls/riched20/editor.c
P wine/dlls/riched20/paint.c
were modified in this interval. The regression causes the open-source
KeyNote note editor (http://keynote.sf.net) to crash after a few clicks
through the sample note file. More information and screenshot in bugzilla
entry: http://bugs.winehq.org/show_bug.cgi?id=5769

If you need more information, please be very explicit in your instructions
about how I should get it. I have little experience with the
development\debugging side of Linux. Thanks a lot for Wine in all its glory!
