Bug 14162 – Page crash then causes launch crash

• Component: WebCore Misc.
• Status: RESOLVED INVALID

[Kevin M. Dean]

When I go to the above link and click watch Trailer, Webkit crashes. Then when I restart Webkit it crashes repeatedly on launch. The only thing that fixes it, is to launch Safari 3 and go to the Advanced preferences, deselect my custom style sheet and quit. Now I can restart Webkit without crashing and reset my stylesheet. I've had this occur while browsing other sites to where restarting would crash until I unset my stylesheet to fix.

I'm attaching a series of crash logs that shows the initial crash, then subsequent restart crashes and then after clearing the stylesheet, an initial crash again, etc.

Also note that the restart crashes doesn't occur unless you already have a stylesheet selected before the initial crash.

This appears to be caused by a QuickTime component that attempts to access WebKit from inside a QuickTime callback.  It's hard to tell though as you attached 5 or 6 crash logs which all have different stack traces.  A bunch of them show the same WMV codec in the stack though, so I would suggest you remove that and see if the crashes go away.  If they do, please file a bug report with the developer of that software and close this as INVALID.

Removing the Flip4mac plugins does stop the crash, but are you sure it's their bug. Safari 3 beta doesn't crash. It only crashes when I'm running the latest nightly. Also the other crash logs are crashes when I try to restart Webkit. It continues to crash with the different traces until I remove the stylesheet like I mentioned above. I've recently had other stylesheet related crashes that were fixed like Bug 13880, so maybe there is still something else there causing crashes. This new stylesheet crash only seems to occur after another possibly unrelated crash, which then creates the situation where Webkit crashes on start until I remove that stylesheet setting in Safari. Setting the stylesheet back within Webkit works fine even after restarts until I crash on a site again. It's really odd.

No, I'm not sure it's the Flip4Mac codecs fault.  The stack trace just shows rather unexpected behaviour.  The Esellerate component used by the Flip4Mac WMV importer QuickTime component (/Library/QuickTime/Flip4Mac WMV Import.component/) is attempting to allocate a WebView from within a QuickTime callback which is being called within a NSURLConnection callback.  It's not clear why this would crash, and I don't recall any recent changes being made around the area which the crash appears to be happening.

The site above no longer shows a page and I haven't had a similar crash in ages, so I'm just marking this as invalid.
