Tdesktop: Unexpected crash on Arch Linux
Steps to reproduce
Unfortunately, none. It happens sometimes.
Apparently this is due to Qt related issues.
Configuration
Operating system: Arch Linux x86_64 4.19.8-arch1-1-ARCH
Version of Telegram Desktop: v.1.5.1
Used theme: Night theme

Also... I'm experiencing a change in font style.
QApplication: invalid style override passed, ignoring it.

The change in font style comes from a patch from the Arch maintainers: https://git.archlinux.org/svntogit/community.git/commit/trunk?h=packages/telegram-desktop&id=710af675a41f555b18359bb37e9ce78f50bb6d6f
Does the crash also happen with the official version? Looks like a crash in the inputcontextplugin, but as long as you cannot reproduce it reliably, this should be hard to debug.

I'll try to install the official version and let you know

Apparently, this crash doesn't happen on the official client.
Probably the telegram-desktop arch package mantainers screwed up something with the latest patches.

on 12 Dec 2018
To be honest, I do not get a crash on the repo version either, maybe they missed some required dependency for the inputcontextplugin or something

on 13 Dec 2018
BTW, to fix the font, you have to install the optional dependency ttf-opensans

Is this cause of the bleeding-edge Qt5? Or the patches archlinux-community's packages manager uses? Should we open a bug report? Could it be some differences in archlinux's qt5 build flags?

This is a related issue in ArchLinux Bugtracker.
@PedroHLC What Linux distro do you use? I use Arch as well as @Hyd3L.

@daskol @Hyd3L Could you install unofficial qt5-*-debug packages from [1] to get a useful stack trace?
