Error in sending message - Error 38: 'can not parse arg #1' with [disable_preview]

The problem

I have simple script that sending a message, but sometimes it sends message, sometimes not

Your environment

Fill out your used versions:

Component	Version
python	3.4.3 <!-- $ python --version; -->
pytg	0.4.10
OS	Ubuntu 14.04.2 LTS

Steps to reproduce

my code is:

import logging
logging.basicConfig(level=logging.DEBUG)
import time
from pytg import Telegram
d = open('/root/stock/stocks.txt', 'a+')
tg = Telegram(telegram="/root/tg2/bin/telegram-cli", pubkey_file="/root/tg2/tg-server.pub")
sender = tg.sender
sender.send_msg("miaow2", "/stock")
time.sleep(3)
histo = sender.history("miaow2", limit=0, offset=1)
stock = histo[39]
d.write(stock['text'] + '\n')
sender.safe_quit()
d.close()

Send dialog_list in telegram-cli, then start to use pytg should fix the problem. At least it works for me…

I’ve faced this problem and it seems to be from CLI, when you get the history from cli directly you get error: {"result": "FAIL", "error_code": 78, "error": "can not parse arg #1"}

But when you do a contact_list first and then get history it returns the history and now the script could be run it seems to a problem with the CLI
