wine users - Jun 2011 - missing dbghelp.dll 6.0.7.0 or higher (LotRO)

Last night I started getting an error message in Lord of the Rings Online:

"Debugging help functions could not be loaded. Please make sure you have 
version 6.0.7.0 or greater of dbghelp.dll you can put this dll anywhere 
in your path except your system32 directory. If you do not have this dll 
then you can get it by installing the Debugging Tools for Windows 
Package from \\socrates\public\Debugging Tools For Windows\  or the 
latest version from 
http://microsoft.com/whdc/devtools/debugging/default.mspx."


The error says where to put the file if you are in windows, is that any 
different in Wine?


More info on what is happening when I get the error in case it's needed:
This error started happening out of the blue, I had loaded the game 
earlier in the day with no problems and made no changes to wine or ran 
any game patches between then and the error. The error is now 
consistent, occuring every time I load the game between the pylotro 
launcher and the game launch itself. After the error box I get video 
corruption of my entire screen, multicolored lines and boxes. If I click 
for the error box to go away the video corruption also goes away and the 
game launches and plays normally. After closing the game the video 
corruption returns along with my normal desktop. Sometimes restarting X 
through ctrl-alt-backspace clears it, sometimes it takes a full reboot.

Wine 1.3.21 installed through package manager (OpenSuse 11.4, KDE)
Nvidia 460, driver 256.53

Try upgrading your driver. Or at least reinstall it. If the problem persists,
post complete terminal output (if it's big, please use pastebin).
