WebCore involved in crashes

WebCore is part of WebKit which is the Safari engine available for use in Mac OS X applications. Entourage uses it to render HTML messages. Microsoft & Apple are investigating the WebKit-related crashing.
Currently some users are experiencing crashes and will see this in their crash logs. Not all users are seeing the problem.

Application Version: 12.2.0.090605
Crashed Module Name: WebCore

For most users, upgrading from the Safari 4 beta to the final release fixed the issue. Others reported that SP2 fixed the issue for them. Be sure you download and install all the latest updates for Office and the OS. I suggest testing in a new User to eliminate problems in your User’s account as part of the problem.
Until the issue is resolved…..

Use the Apple Combo Updater

The Apple combo updater refreshes old files so I suggest downloading the combo rather than use Software Updater to download the incremental updater. Combo updaters will install on the same version as they’re applying–no need to roll back or do a clean install. More info

Leopard
Mac OS X 10.5.8 Combo Update (For both PowerPC- and Intel-based Macs )

Tiger:
Mac OS X 10.4.11 Combo Update (PPC)
Mac OS X 10.4.11 Combo Update (Intel)

Update Microsoft Office 2008 for Mac

Office 2008 for Mac 12.2.0 (SP2) (requires Office 2008 for Mac 12.1.0 be installed)
Office 2008 for Mac 12.2.1


[Note added Sept 2010: this issue was never resolved for many Entourage users. Upgrade to Outlook 2011.]

Test in a new User

Since not all users are experiencing the problems, be sure there is no corruption in your setup.
Testing in a new User will quickly tell you if the problem is system wide or if it’s your User’s folder that contains the problem.

  1. Troubleshooting Entourage in a New User Account
  2. Troubleshooting Your User Account for a Problem

When testing in Your User’s account, most likely it’s not your Entourage Identity. Do steps 2,3 and 5.

  • 2-Test for corrupt Microsoft preferences
  • 3-Test for other preference conflicts/corruption
  • 5-Test for a corrupt font

Test for other preference conflicts/corruption involves deleting cache files. There are several utilities to help delete caches. See Tools for Troubleshooting

Note: the Entourage Spotlight cache files could also be deleted with these utilities. Entourage will rebuild these, but it’s not necessary to delete as these are not the type of cache files involved in this type of crash.
Entourage 2008 & Spotlight explains where these Spotlight cache files are located and how they are used.

    I have discovered something that I suggest all entourage 2008 users check if using entourage 2008 behind a proxy.
    If you find you are using a pac file proxy configuration (Automatic proxy configuration) and you are finding entourage crashing please switch over to a manual proxy configuration.
    I found since switching over entourage has not crashed once.
    After discussion with our IT department outlook for windows does encounter similar issues on occasion, but I’ve been told other Mac apps have similar issues using proxy pac configuration.
    If you find this change has solved your crashing issues please let me know so other users don’t suffer from entourage crashing constantly.
    If possible please post this for the benefit of other users on your blog.
    I’ve change my proxy settings as I’ve suggested and not a single crash has occurred since.
    Thanks.
    Jon.

    Any word on this? We support tons of Entourage 2008 users and 80% of them are experiencing this crash on a daily basis on certain HTML emails. It seems to span all kinds of environments. 10.5/10.6, Intel/PPC, various update levels.
    Thanks!

  • There is nothing new to report. If you could send me an example, I’ll be happy to see what happens on my computer. Look for my message to your with an address for sending the sample.

    Hi All,
    Is there any news on whether or not this issue will be fixed
    Thanks in Advance

  • Since there has been no fix issued, I would assume it’s not going to be fixed.
    Try deleting “Tasman Browser.cache” and “com.microsoft.browserfont.cache” in ~/Library/Caches to see if that helps. It’s possible other cache files might be involved.
    Note: Not all versions of Entourage use the “Tasman Browser.cache”
