Public bug reported:

Hi together,
I found an interesting bug today. After compiling attached errornous latex code 
attached in my home directory, nautilus crashes a second after start with 
segmentation fault. Ouptut is:
<output>
** (nautilus:4779): WARNING **: Couldn't register with accessibility bus: Did 
not receive a reply. Possible causes include: the remote application did not 
send a reply, the message bus security policy blocked the reply, the reply 
timeout expired, or the network connection was broken.

Speicherzugriffsfehler
</output>
("Datei oder Verzeichnis nicht gefunden" means "file or directory not found", 
"Speicherzugriffsfehler" means segmentation fault).
I have no idea why the produces pdf is malious, but it shouldn't matter because 
nautilus should be able to handle such files by ignoring them somehow.
Removing the pdf file from my home diretory fixes the issue, compiling it again 
makes it reproducible.
I'm running nautilus  3.8.2 on Ubuntu 13.10.
