Bug Description

The behaviour is reproducible for me (meaning each time I do the above, this results in a crash and I have to delete config file and cache.

I clicked security vulnerability, because this bug can be used for a denial of service attack. Though, I am not a tech person, so your definition on this might differ.

I have the same behaviour on my BQ4.5 using Ubuntu 15.04 (OTA-13) and Telegram version (updated 22.11.2016).
The app was working fine when I used open chats. But now I'm switching to secret chats and this is where the trouble began:

* I received a new message and tried to open it ... Telegram appears for ca. 3-5 seconds, showing the overview of the chat members and then just disappears. No crash message had been created (auto-send-errors enabled)
* Rebooting didn't work
* removing - rebooting - reinstalling - rebooting using the Ubuntu App Store didn't work.
* Today I found this which suggested deleting the Telegram config and cache ... IT HELPED!

Now I lost all secret chats, but I can use Telegram as I did before.

Well I did a few tests, sending stickers from an IOS-device via Telegram secret message.
Instead of the sticker I see this message: "You have invited <me> to join a secret chat" ... even I received messages before. Sending stickers from my BQ4.5 never arrived at my iphone, but Telegram (Ubuntu) quoted to checks as if it arrived normally ...
Very strange "Sticker"-behaviour.
Rest works fine, text, links, icons, pictures ... only the stickers fail.

I did this test to reproduce the Telegram crash on start up ... but couldn’t repeat it.
