Random crashes when going through channels

[15bit]

Sometimes going through the channel list it crashes with the following traceback.

Traceback (most recent call last):

I also get this sometimes when logging into nctelegram after loading up telegram-cli. The error looks very similar to the above one.

bind: Address already in use
Traceback (most recent call last):
  File "/usr/bin/nctelegram", line 70, in <module>
    ncTelegram.Telegram_ui(config_full)
  File "/usr/lib/python3.5/site-packages/ncTelegram/__init__.py", line 69, in __init__
    self.msg_widget = MessageWidget(self)

KeyError: 'first_name'

This should be fixed now, because I have no way of testing it, please tell me if this error is still there.

PS: in your second backtrace the error bind: Address already in use is present, this means that telegram-cli was still running when nctelegram started, kill it before restarting nctelegram.

Pulling from git now - I'll let you know shortly :)
