.exe crashes in gfx User Font Set::On Load Complete when using CSS with @font-face
User Agent: Mozilla/5.0 (Windows NT 5.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2 Build ID: 20110902133214 Steps to reproduce: 1. Create a XULRunner application that uses @font-face CSS declaration to load a font from a URL. 2. Launch the application using xulrunner-stub.exe Actual results: The application crashes on startup. Expected results: The application should have started normally and used the applied font. Launching the same application using xulrunner.exe -app path/to/application.ini works as expected.

Scoobidiver, this is a bug filed against XULRunner version 11.
It seems a dupe of bug 730550 (same stack trace). Does it happen with Aurora 13 or Nightly?

It still happens with Aurora 13.0a2 (2012-03-17-04-20-20-mozilla-aurora).

I'm guessing this is bug 730550. The fix there checks for t2embed but it doesn't assure that the proc address of t2embed functions are non-null (if a dummy lib is used for example).

If you look carefully at the fix, it will prevent failure in the case that t2embed.dll is missing but not if it has been replaced by a dummy lib. The list of dll's includes t2embed.dll and yet the crash occurs. For anyone that can reproduce this, what is the size/date/version of the t2embed.dll? I think we probably need to undo the changes that were originally made, such that if the proc pointers are null we fail gracefully. The better fix would be to remove the dependence on t2embed.dll completely as it's no longer necessary since the sanitizer code rebuilds the font anyways.
This patch is not a simple backout in two ways. 1. Try to load t2embed library only once. Before bug 699247, library load was tried everytime gfxGDIFontList is initialized. 2. Fallback to AddFontMemResourceEx path if t2embed library or functions are unavailable.
