Since feedparser messes with Python’s internals by assigning
to __code__ it needs to import SGMLParseError too. It also
expects SGMLParseError, which was turned into AssertionError by
https://github.com/python/cpython/commit/e34bbfd61f405eef89e8aa50672b0b25022de320

I noticed that pam_mount mounts work fine when loging into a textual
session, but not when using sddm. This patch fixes this problem by
ensuring that pam_mount.so is included in /etc/pam.d/sddm config file.
