If you really want something simple and know how to write/run Python, take a look at the script Bas Bosschert: sources
#!/usr/bin/env python
import sys
from Crypto.Cipher import AES
try:
wafile=sys.argv[1]
except:
print "Usage: %s <msgstore.db.crypt>" % __file__
sys.exit(1)
key = "346a23652a46392b4d73257c67317e352e3372482177652c".decode('hex')
cipher = AES.new(key,1)
open('msgstore.db',"wb").write(cipher.decrypt(open(wafile,"rb").read()))

Pritam Baral has mentioned an even simpler way:
openssl aes-192-ecb -d -in msgstore.db.crypt -out msgstore.db -K 346a23652a46392b4d73257c67317e352e3372482177652c
