AutoGK crash +richedit trace

Tested in 1.1.21 and 1.1.22 on openSUSE 11.1.

AutoGK is a free, user-friendly front end for Avisynth and VirtualDubMod that
automates the encoding process. It needs native msvfw32 and mfc42u to encode
video in Wine, however, these overrides are not needed to start up the program
and reproduce the crash, which only occurs on closing the program.

To reproduce:

Download and install AutoGK. (Installing in a virtual desktop works best.)
Run it from the program directory. 
Close the program by clicking the close button in the upper right corner.

AutoGK will crash, showing a dialog that says "Exception EAccessViolation in
module AutoGK.exe at 00001F1B. Access violation at address 00401F1B in module
'AutoGK.exe'. Read of address 00000000."

Using native riched20 solves the problem.
