seamonkey fails to start, strace complains about files in /usr/lib/xulrunner

[Carl Fink]

Binary package hint: seamonkey

I updated my system this morning, then restarted. Now seamonkey won't start, and when run in strace complains about certain files being nonexistent or having incorrect permissions:

open("/usr/lib/xulrunner/components/xpti.dat.tmp", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = -1 EACCES (Permission denied)
open("/usr/lib/xulrunner/components/compreg.dat.tmp", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0664) = -1 EACCES (Permission denied)
gettimeofday({1253656300, 605562}, NULL) = 0
stat64("/usr/lib/xulrunner/components/compreg.dat", 0xbfd45e24) = -1 ENOENT (No such file or directory)
lstat64("/usr/lib/xulrunner/components/compreg.dat", 0xbfd45e24) = -1 ENOENT (No such file or directory)
access("/usr/lib/xulrunner/xpicleanup.dat", F_OK) = -1 ENOENT (No such file or directory)
read(7, "\372"..., 1) = 1
close(7) = 0
close(8) = 0
open("/usr/lib/xulrunner/components/compreg.dat.tmp", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0664) = -1 EACCES (Permission denied)
brk(0x9243000) = 0x9243000
brk(0x9242000) = 0x9242000
brk(0x9241000) = 0x9241000
brk(0x9240000) = 0x9240000
brk(0x9238000) = 0x9238000
brk(0x9237000) = 0x9237000
brk(0x9236000) = 0x9236000
brk(0x9235000) = 0x9235000
brk(0x9234000) = 0x9234000
exit_group(1) = ?

The same happens whether I start it as browser, composer, or mailer.

I'll be glad to do anything I can to help debug this.

Thanks for any help,
Carl Fink
