Printing issue - additional error message

Running v11.52 on WinXP Pro SP3 -- have experienced problems with printing from webpages over many Opera versions in the past couple of years that have produced outright crashes which I've always reported through the built-in crash reporting function. Most of these crashes are preceded by a popup notice that "Shockwave Flash plugin has failed -- a restart of Opera is recommended" before the UI disappears and (most times) the crash reporting window pops up. I recently updated with the latest releases of Flash and Shockwave, so perhaps those are contributing factors.

Today, there was a wrinkle in the usual routine -- after toggling "print preview" of a WaPo webpage (http://www.washingtonpost.com/blogs/federal-eye/post/postal-service-to-customers-we-want-our-stuff-back/2011/11/09/gIQAembV5M_blog.html?hpid=z11) where there is no embedded print option available, the usual "Shockwave Flash plugin failed" message appeared and I clicked the "OK" box. Immediately afterwards, Opera locked up completely (the UI contents frozen and totally non-responsive) and a second box appeared with the following information:

Microsoft Visual C++ Runtime Library
Runtime Error!
Program C:\Program Files\Opera\Opera.exe
R6025
- pure virtual function call

I then had to use Task Manager to manually kill the Opera process (I typically kill the entire process tree when this step is required), then rebooted the OS and relaunched Opera, choosing to "continue from last time" when that box appeared so I'd have all of the 6 tabs that were open back.

I know this is a longrunning problem with print rendering, but since it's the first time the Visual C++ error message has appeared I thought I'd pass it along for anyone on the development team who is trying to wrestle with this particular bug.
