Jyrki, are you able to reproduce the second crash?
Jyrki Wahlstedt
Comment 9 2011-01-21 00:53:43 PST
Hmm, odd, but good if stays this way, could install ClickToFlash in r76334 (from archive), so obviously couldn't reproduce the second.

I've changed from WinXP to Win7 (broken disk, change not necessarily to better, but anyhow), so I am not able to provide any status checks anymore. Generally, however, I saw no repeatable crashes before the (disk & OS) change, so I'd say by me it's ok.

Comment 10 showed that user was not able to reproduce this crash and also AppleWin port is gone and crash logs are from Windows XP and might not be super relevant and only `win-cairo` port is maintained and we don't support plugins so it would be difficult to reproduce this in today's environment. Marking this as 'RESOLVED WONTFIX'.
