User picture permissions can cause Prefs crash System
I am running 10.1.5 on a TiBook with 512 Mb of RAM. Recently, the System Prefs application would "unexpectedly quit" whenever I tried to either edit an existing user or create a new user. I debugged it by launching Console (in /Applications -> Utilities) and watched the error message as I tried to edit a user. The error message said that it was unable to open a TIFF. Hmmm...

I navigated to Library -> User Pictures and checked out the permissions on the pictures that I had assigned for the current users. Lo and behold the permissions for the two pictures that were assigned to the two users were different that the other pictures that I had not used. I changed the two to match the other pics and voila, my System Prefs app no longer crashes. I even created a new user with no problems. Hope this helps somebody.

[Editor's note: It appears that correct permissions are rw-rw-r--, which can be set via a "sudo chmod u=rw,g=rw,o=r pic_name.tiff" or "sudo chmod 664 pic_name.tiff" (I think I got that right). Running the "Repair Disk Permissions" tool on the First Aid tab of Disk Copy might also fix this problem, but I haven't tested it myself.]

true, repair perms will fix this. the bigger question to ask is how they get out of rev in the first place. it's rather alarming that there are so many of these permissions issues...

$ lsbom -p fM /Library/Receipts/*/contents/ | grep -i 'user pictures'
./Library/User Pictures drwxrwxr-x
./Library/User Pictures/Animals drwxrwxr-x
./Library/User Pictures/Animals/Butterfly.tif -rw-rw-r--
./Library/User Pictures/Animals/Cat.tif -rw-rw-r--
./Library/User Pictures/Animals/Dog.tif -rw-rw-r--
./Library/User Pictures/Animals/Dragonfly.tif -rw-rw-r--
