webkit.dll crash on launch

Hello. I tried posting on this issue in the Flex forums a couple weeks ago, but got no response. I am posting here in case the problem in case it is more specific to AIR applications in general.

At least one user of our  Flex desktop application, who was formerly able to run it normally, now  has an issue in which the application crashes shortly after opening.  Facts:

• The user is running Windows XP SP3.
• The  Application event log shows "Faulting application MyAppName.exe,  version 0.0.0.0, faulting module webkit.dll, version 0.0.0.0, fault  address 0x001f9425."
• The crash does not always happen at exactly  the same time (although is always within a few seconds), and the  application is able to download a few things before crashing.
• Uninstalling and reinstalling the latest version of AIR on the user's machine did not help.
• Running Tour de Flex produces an equivalent message.
• The  only potentially relevant thing that the user mentioned that has  happened recently is that she installed another AIR app, svBuilder.  However, since AIR was reinstalled more recently than the application  was installed, I don't see how that could be related. Installing  svBuilder on other computers also does not appear to induce this  problem.
  
• I found at least one example of another AIR application having the same problem.
  

If anyone has any idea what the problem could be here, please let me know.

Thanks,

Chris
