Crash Data

Since upgrading to the 20100408 nightly, closing a tab with flash loaded crashes that tab. 

Disabling OOPP and no crash.  User does have ABP enabled and confirmed that disabling ABP results in no crashes even with OOPP enabled.  A user on mozillazine also reported this today.  See

Opened a bug report with Wladimir
I was able to reproduce this at

The video there does not load (just a black screen) closing the tab while testing with disabling OOPP, ABP and flashblock and I got a crash with the same signature.
Also happening in Mac OS X 10.6.3, OOPP enabled, Flash 10.1 RC1.

I have installed ABP in current Minefield builds on Windows 7 and Mac OS X 10.6 and I'm unable to reproduce this. Do I need to specially configure ABP?
Do you have an rules setup via a subscription?
I have a default ABP install.
you have to subscribe to filters. Go tot Filters in the ABP menu bar and click on Add Filter Subscription.  When the dialog pops up select Easylist.

Subscribing to any filter is not resolving problem

> Subscribing to any filter is not resolving problem

You have to have filters in order to get the crash.  If you don't have filters you don't crash.
The crash happens if Adblock Plus blocks any of the object subrequests sent off by Flash. One filter is enough - go to menu Tools / Adblock Plus Preferences, press Delete to remove everything you have and click "Add filter" then: "|*". Press Enter and click OK. With this filter a YouTube video will crash you.
Blocks: abp
I can reproduce this now.

This is a regression from bug 554524, I'm going to back out when the tree opens.

Marcia, you should open a new bug. You had the same crash signature, but it's definitely not the same cause.
