Bug 17073 – Safari auto-quits on SVG-enhanced page when Adobe plug-in v3 installed

• Status: RESOLVED
• Resolution: INVALID
• Component: SVG

[Henri Sivonen]

Seen in Safari 3.0.4 and r29844 on PPC (G5) Mac OS X 10.5.1.

Reproducible:
Always.

Steps to reproduce:
1) Load http://my.opera.com/MacDev_ed/blog/2008/01/22/core-web

Actual result:
The app auto-quits. No crash reporter.

Expected results:
Expected the page to render.

Additional info:
I'm not seeing this when WebKit is embedded in NetNewsWire and doesn't display SVG.

[Eric Seidel (no email)]

I don't see this crash on TOT.  My 3.0.4 instance is too full of useful pages at the moment to test a crasher on it. :)

[Mark Rowe (bdash)]

I cannot reproduce this with Safari 3.0.4 on Mac OS X 10.5, nor with latest SVN.

[Mark Rowe (bdash)]

Can you check the system console for any relevant log output from Safari?

[Henri Sivonen]

Nothing in console, but this SVG image alone is enough to trigger this:

[Mark Rowe (bdash)]

I still can't reproduce.  Can you please run Safari under GDB and paste the output that is displayed when it "quits" while viewing this SVG?

[Henri Sivonen]

gdb says:
Program exited normally.

[Mark Rowe (bdash)]

Do you have any Safari extensions installed?  What about plugins that may be taking over the rendering of SVG (eg, the Adobe SVG plugin)?

If you're familiar with gdb I would appreciate if you could set a breakpoint on exit, and then get a backtrace at the point which it is called.  Something like the following:

(gdb) b exit
[0] cancel
[1] all

Non-debugging symbols:
[2]    +[NSThread exit]
[3]    exit
> 3
Breakpoint 3 at 0x92850415
(gdb) r
Breakpoint 3, 0x92850415 in exit ()
(gdb) bt


Thanks!

[Henri Sivonen]

Sorry the question fell through the cracks. Here's the backtrace:
(gdb) b exit
[0] cancel
[1] all

Non-debugging symbols:
[2]    +[NSThread exit]
[3]    exit
> 3

Looks like a plug-in.

It turns out I had the Adobe plug-in even though I thought I did not. Uninstalling it solved the problem.

[Mark Rowe (bdash)]

Thanks for following up on this!  That backtrace definitely shows that the Adobe plug-in is terminating the process for some reason.  Sadly there's not much that we can do about that.  I'm closing this bug as INVALID to indicate that the issue is outside of WebKit.  Thanks again for following up on this.
