I checked out and built the WebKit in debug mode, around 8pm today, then launched Mail from the Terminal: WebKit/WebKitTools/Scripts/run-webkit-app Mail --debug Apparently WebCore crashes every time I select a HTML mail and click Reply. I get the same crash when I launch Mail under Debugger (after adding it as Executable in WebKit.xcodeproj) due to an ASSERT in WebCore::MainResourceLoader::didReceiveData, because 'data' is null. It doesn't crash when displaying the HTML mail (for instance, a mail with CSS3 columns is displayed correctly in the 3-pane window). It only crashes after clicking Reply. Also it doesn't crash when replying to plain text messages, only to HTML messages (any kind of HTML, even a simple FONT FACE). Unfortunately I don't have enough history with the WebKit to confirm whether this is a recent regression or not. However some work has been done recently to fix crashes that show WebCore::ResourceLoader::didReceiveData towards the bottom of the stack in bug 12458 (checked in this morning) and bug 12444 (checked in this afternoon). See also bug 12365 (checked in 2007-01-25) and maybe bug 12355 (checked in 2007-01-21).

Hi Piet! Thanks for submitting this bug. Could you post a stack trace of the crash (either as a comment or as an attachment to this bug)? Also, could you provide the Subversion revision number (rNNNNN) used when you reproduced the crash? Use the "svn info" command to get that number.

Confirmed with a locally-built debug build of WebKit r19301 with Mail 2.1 (752/752.2) on Mac OS X 10.4.8 (8L127). Steps to reproduce: 1. Start Mail with WebKit ToT. 2. Open an HTML mail message. 3. Click "Reply" button. Expected results: A window should open to reply to the message. Actual results: Mail crashes. Notes: If you replace Step 2 with "Highlight HTML mail message", Mail doesn't crash, but the reply only has a single empty line when the reply is quoted. "Responding" Preferences: - Use the same message format as the original message: checked - Quote the text of the original message: checked - Increase quote level: checked - When quoting text in replies or forward: selected "Include selected text if any, otherwise include all"

I updated my tree. The problem is still there, same stack and all, only with HTML mails. Reopening.

(In reply to comment #2) > Steps to reproduce: > > 1. Start Mail with WebKit ToT. > 2. Open an HTML mail message. > 3. Click "Reply" button. Note that it is VERY IMPORTANT not to click anywhere in the message after opening it--open it,then click the "Reply" button. Still reproducible with a local debug build of WebKit r19337.

I confirm: same problem here with r19341. If you click the Mail first (simple click, or click-n-drag to select some text), it doesn't run into the ASSERT.
