As a first guess, I'm filing this on Parser because it only happens if the document is HTML (not XHTML). It could be just about anything, though... viewer freezes on showing the test case to be attached, which contains a select element (with a few options) inside a p element (div works too). This freezes viewer while it is loading the document. I've seen select elements many other places, so it may only happen in certain simple cases (particularly when not inside a form). Removing the p or div fixes the freeze, as does putting a form around the p or div. It freezes after showing the following in the text window: Using '/home/david/mozilla/src/mozilla/dist/bin' as the resource: base Got the event queue from the service Calling gdk_input_add with event queue Reading file... Reading file...Done Reading file...
