PS: You could take a look at the apt related log files, but most likely
the issue isn't related to an upgrade.

[rocketmouse at archlinux ~]$ ls -hAl /mnt/moonstudio/var/log/apt/ 
total 3.3M
-rw-r--r-- 1 root root 474K Oct 12 09:31 history.log
-rw-r--r-- 1 root root  13K Aug  5  2015 history.log.1.gz
-rw-r----- 1 root adm  2.7M Oct 12 09:31 term.log
-rw-r----- 1 root adm   40K Aug  5  2015 term.log.1.gz

For you the path would be /var/log/apt/ ;). I doubt that even if a
dependency was upgraded, that it would cause the issue you experience.
