pacman removed expat with pidgin-libnotify

I just removed the package pidgin-libnotify with the command pacman -Rscn pidgin-libnotify and it also removed the package expat, I didnt know what it was until it was to late.

Remove (3): pidgin-libnotify-0.14-4  perl-xml-parser-2.40-2  expat-2.0.1-6

Total Removed Size:   1.44 MB

Do you want to remove these packages? [Y/n] 
(1/3) removing pidgin-libnotify                    [######################] 100%
(2/3) removing perl-xml-parser                     [######################] 100%
(3/3) removing expat                               [######################] 100%

Why did it remove expat? It totaly broke my system:

$ sudo pacman -Syu    
pacman: error while loading shared libraries: libexpat.so.1: cannot open shared object file: No such file or directory

I did solved it by manually copying the files to its right place from the tar.gz file. But I dont understand why it removed a package from core.

So what is going on here? One, I don't see any libarchive output at all (is it installed). Two, you clearly upgraded to pacman 3.5.0 from testing, upgraded your local database, and then downgraded back to 3.4.3 on March 20th, which is why you see all those "error: could not open file /var/lib/pacman/local/pacman-3.4.3-1/depends: No such file or directory" errors you seem fine with ignoring.

When you did the -Rcs operation with an upgraded local DB, you hosed your system because the old version of pacman wasn't able to actually read the dependency information. Note in your output above how pacman lists no depends at all- clearly not the case.

A lesson to all- you cannot downgrade from 3.5.X once you have upgraded. And including said details in your first post would have been quite helpful.
