[Solved] System is looking for wrong shared library version

Question

Hey guys.
Today I installed updates on my two arch machines, both running SLiM + XFCE4, using `pacman -Syu`. The update on one machine worked like a charm, but broke the other.
When booting and trying to login with SLiM, the screen goes black and I'm back at SLiM. The log shows this:
xfce4-session: error while loading shared libraries: libicule.so.50: cannot open shared object file: No such file or directory
Of course there is no such file, because I installed icu 51.1-1 and there is only libicule.so.51 in /usr/lib/.
I tried to re-download and re-install icu and xfce4-session in rescue mode, or creating a symlink for libicule.so.50 pointing to the new, but nothing changed. I always drop back to SLiM. On the second system there is no error, I installed the new icu package, rebooted and logged in as usual.
I downgraded to icu 50.1.2-1 and I can login again. But it seems that some other applications are breaking now. (vim e.g.)
Any ideas how to fix this?

Answer 1

Today I tried to update icu along with lib32-icu, but the result was the same. Still looking for libicule.so.50.
I have run `ldconfig -v` to check the symlinks, and it uses the v51 library.
And it seems not be to be a XFCE related problem, when installing v51 I can't even start vim because it also wants v50. So it has to be something other.
On both systems, the LD_LIBRARY_PATH variable is blank. When running `ldd /usr/bin/xfce4-session`, it get the same result as running it. One machine said "not found" because looking for v50, the other is using v51 and all okay.
Maybe some problem with the dynamic linker? I'm not very familiar with libraries and linking stuff.
