I have been able to reproduce the crash on Windows XP. I will investigate.

The problem also shows up in Eclipse 3.6 and Eclipse 3.5, it only happens when the href to the PDF document contains an anchor as in <topic href="dz9zr006.pdf#G29.1169203" >. The problem does not reproduce if an external browser is used.

I'm surprised this has not been reported before since it exists at least back to Eclipse 3.5. The help system browser on Windows uses Internet Explorer to open the pdf file, I don't yet know if the problem is specific to one version of IE.

I have IE 8 on my system, which version were you using?
Comment 5 Samuel Wu CLA 2011-01-12 13:10:21 EST 
My IE is 7.0.5730.13. But I was not using to open the help page. The preferences setting for Open help contents is "In the help browser".
Comment 6 Chris Goldthorpe CLA 2011-01-12 13:33:00 EST 
When you open using the help browser on Windows you are indirectly using Internet Explorer - the SWT Browser widget is built on top of the native browser services, on Windows it uses Internet Explorer.

I noticed there was a patch appended to bug 334161. Is that patch supposed for this bug? Wonder how to try it out. Failed to find the ScopeSelectPart in the plug-in org.eclipse.help.ui.

I tried the patch attached to bug 334161 and it does fix this problem!
Comment 9 Chris Goldthorpe CLA 2011-01-19 16:44:50 EST 
I verified using M20110119-0834 that this is now fixed by the patch in Bug 334161
