11863 2006-12-17 16:27:54 -0800 REGRESSION: Reproducible crash in GMail after composing new message, clicking in body, then closing window 2006-12-17 18:04:48 -0800 1 1 1 Unclassified WebKit Page Loading 420+ Mac OS X 10.4 RESOLVED DUPLICATE 11729 http://mail.google.com/mail/ GoogleBug, Regression P1 Normal --- 1 ddkilzer webkit-unassigned oldest_to_newest 41546 0 ddkilzer 2006-12-17 16:27:54 -0800 Summary: Logging into GMail, composing a new message, clicking in the body textarea, then immediately closing the window causes a crash a few seconds after the window closes. Steps to reproduce (taken from Bug 11859 Comment #2): 1. Start WebKit nightly r18244 or r18260. 2. Log into GMail. 3. Click "Compose Mail" link. 4. Click once in the message body textarea. 5. Close the window immediately after clicking. 6. Wait about 5 seconds. 7. WebKit crashes. Expected results: WebKit should not crash. Actual results: WebKit crashes. Regression: Regression from earlier WebKit builds that worked with GMail's wysiwyg editor. Notes: The "top" of the stack trace appears to varie (e.g. where the crash occurs), but it always occurs. Here's a stack trace from a locally-built debug build of WebKit r18269 with Safari 2.0.4 (419.3) on Mac OS X 10.4.8 (8L127).

The new message "textarea" is actually a contenteditable iframe which would explain why it crashes and the backtrace is nearly identical (the one attached to 11729 is from a nightly which is why its shorter). 41438 2 ddkilzer 2006-12-17 18:04:48 -0800 Thanks, Matt! *** This bug has been marked as a duplicate of 11729 ***
