If my understanding of Mozilla's internals is correct, cairo
isn't involved with popups at all. At least not for Firefox

Not really. A backtrace might help. And a more detailed description
on your build setup, too. As you are building with cairo 1.4.4, I take
it that you are using --enable-system-cairo?

Although several Mozilla developers read this list, perhaps you should
also open a bug on Bugzilla...
