Kernel protection failure?

[Quianam]

If anyone has a solution for this, I would really appreciate it.

Yesterday, I tried to open Safari and got this error:

EXC_BAD_ACCESS (0x0001)
KERN_PROTECTION_FAILURE (0x0002) at 0x00000020

Thread 0 crashed
0 objc_msg_Send_rtp+24

It listed other threads, but I didn't think I needed to post that here. I can if it would be helpful.

I did not install/upgrade RAM recently, which seems to be the most common source of the error. About a week ago, I installed the plugin SafariBlock, although I haven't had any other issues with it. I am running 10.4.11 on a PowerPC G4, I have plugged in:
A pair of Altec Lansing speakers model number ACS 300.1
Logitech USB headphones
Saitek USB hub with an Epson Stylus CX3810, USB cord of a PlayStation Portable, and a Flash drive, although the flash drive was not plugged in when the problem occurred.

I disconnected all of this, and it did not help. Yahoo! Messenger connects fine, as does Firefox, so it's a Safari issue.

I repaired permissions, and deleted SafariBlock, tried re-installing Safari and deleted all temporary files. I cleared my trash and rebooted. I still could not get it to work. Short of sending it in to Apple, does anyone know how to fix this?

A related question:

I have three user accounts, Safari on the admin and tertiary, and Firefox and Safari on the secondary. How can I get Firefox to run on the admin account without downloading it via Safari, so that I can access the Internet on my admin account? This may be a fairly silly question, but I could not figure it out.

If there is any other information I could provide that would be helpful, please let me know.

Thank you very much to anyone who tries to help, I really need to fix this!

First of all, thank you for providing details. It really does help. For the Safari issue did you try launching safari in another account? If not, try it and let us know if it behaves. As far as your firefox question, FF should launch from any account if it is in the Applications folder outside of any user folders. If Safari is sitting underneath a user folder, move it to you applications folder and you can launch it from any user account.

Yes, I tried to launch from both other accounts. I get the standard message "The application Safari quit unexpectedly. Mac OS X and other applications are not affected. etc." Firefox is not sitting underneath a user folder. When I launch it on the non-admin account, a volume pops up on the desktop and it launches. On the admin account, I attempt to launch it, it bounces, the arrow stabalizes (I'm talking about the dock icon, by the way) and then I get a Mozilla crash reporter window. No volume appears on the desktop.

It sounds like you are launching the FF disk image and then launching FF from inside the disk image after it mounts on the desktop. Next time that disk image mounts, Take the FF app and drag and drop it into the applications folder. There even should be a shortcut to the applications folder inside the FF disk image that should be sitting right next to the app. After you do this you will need to drag and drop FF from the applications folder and drop it on the dock after getting rid of the original on the dock.

I had actually already done that, I was launching off the original. Ok, so now the volume does not appear on the desktop, and it launches fine from the same user account, but it still crashes on the admin. Do I need to reboot, or do anything else? This is not the clearest post, so if I need to clarify let me know.

So FF works fine on the non-admin account but not the admin account and Safari is crashing on both accounts, is this correct?

Yes.

The FF thing sounds like a user issue and Safari sounds like a possible system issue, which is really weird to have both at the same time unless you really screwed something up. Try a safe boot by holding down shift key until you get a login screen. Login to your admin account and try both Safari and FF in that account. If all goes well, reboot normally and test again.
