Subject: msttcorefonts: Dead link /var/lib/defoma/fontconfig.d/T/Tahoma.ttf after upgrade causes Iceweasel to crash

Date: Sun, 20 May 2007 12:03:23 +0200

Package: msttcorefonts
Version: 2.1
Severity: important

Hello,

after I upgraded the package from version 2.0 to 2.1 I wondered why Iceweasel crashes. I did a strace and found these lines at the end:
[...]
open("/var/lib/defoma/fontconfig.d/T/Tahoma.ttf", O_RDONLY) = -1 ENOENT (No such                                                                                                       
file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
[...]

I checked the file and this is what I found:

Version 2.1:
# ls -l /var/lib/defoma/fontconfig.d/T/Tahoma.ttf
lrwxrwxrwx 1 root root 50 2007-05-03 18:58 /var/lib/defoma/fontconfig.d/T/Tahoma.ttf -> /usr/share/fonts/truetype/msttcorefonts/Tahoma.ttf

# ls -l /usr/share/fonts/truetype/msttcorefonts/ | grep Tahoma


Version 2.0:
# ls -l /var/lib/defoma/fontconfig.d/T/Tahoma.ttf
lrwxrwxrwx 1 root root 50 2007-05-03 18:58 /var/lib/defoma/fontconfig.d/T/Tahoma.ttf -> /usr/share/fonts/truetype/msttcorefonts/Tahoma.ttf

# ls -l /usr/share/fonts/truetype/msttcorefonts/ | grep Tahoma
lrwxrwxrwx 1 root root     10 2007-05-20 11:56 tahoma.ttf -> Tahoma.ttf
-rw-r--r-- 1 root root 105312 1997-04-01 00:00 Tahoma.ttf


So this upgrade introduces a dead link. I do not know if it is right that Tahoma is missing but I think when it is deleted the link has to be deleted too.

Regards,
Benjamin Eikel

I would even say this is critical, because it breaks unrelated software.

A dangling symlink is indeed not a neat thing to have in a package, but no 
program should be plainly crashing on such a thing. I therefore doubt that 
this is a critical bug against msttcorefonts.

I'll of course clean up the symlink, but I strongly suggest that you don't let 
your package crash on such relatively trivial things, which seams like the 
real solution to this problem.

thanks,
Thijs

Except having this solution sanely implemented will be longer than
fixing the dangling symlinks. I suspect there are more than one case
where dangling symlinks can make gecko crash.

Indeed, that was it. But I had to remove all the Tahoma.ttf links in
/var/lib/defoma, not only the one in fontconfig.d.

Thanks,

JB.
