pacman startup is very slow

Run pacman, with no parameters, it takes a long time

What is the output of time pacman command? Here is mine

$ time pacman
error: no operation specified (use -h for help)

real    0m1.283s
user    0m0.060s
sys     0m0.136s

$ time pacman

real 0m2.428s user 0m0.198s sys 0m0.631s

Earlier runs were slower though.

Also, run it under a debugger, it prints some garbage.

Found this report trying to ascertain if pacman -Ss taking a long time was normal. It's instantaneous on Arch.

$ time pacman
error: no operation specified (use -h for help)

$ time pacman -Ss asdf

Trying to run pacman under strace results in an endless loop eventually of:
