There is not anything random in that bug, is there ? It always crashes, depending on the argument given ?
Also if you could try to recompile pacman with debug symbols, and show the output of "bt full" inside gdb.
http://wiki.archlinux.org/index.php/Debug_-_Getting_Traces#One_package_settings_only
And try downgrading glibc to see if it solves your problem.
But if you are the only one getting the error, it is quite strange...
And which locale are you using ?
Here the output of the new (with -g) compiled version:

The last upgrade of glibc was on 2009-10-28 and yesterday pacman's search worked.
Quite strange...
Martin
PS: Did not downgrade because of dependencies to other libs and tools (binutils, gcc-libs). Should I try it anyway?
I find it interesting that it crashes on a desc containing unicode characters :
desc = 0x89c4f0 "SCIM 한글 (hangul) input method engine for Korean language"
Can you confirm that it always crashes on this description ?
After resuming my machine from hibernation it works without segmentation faults!
Quite mysterious...
If the error occurs again I'm going to inform you.
Thank you for your time.
Martin :)
$ pacSs 한
extra/scim-hangul 0.3.2-2
SCIM 한글 (hangul) input method engine for Korean language
So I can even search for the non-latin characters here at least, and things seem to work. Looks like something got wacky with the glibc/unicode stuff.
