Comment # 26 on bug 1149986 from Marcel Kuehlhorn

Starting with telegram-desktop 2.1.14 beta the patch no longer works.

I've built the current beta with rebased 0000-gtk2-default.patch here:
https://build.opensuse.org/package/show/home:tux93:tdesktop-beta/telegram-desktop

When trying to launch this version of Telegram while
`libqt5-qtstyleplugins-platformtheme-gtk2` is installed on the system startup
hangs with the following messages in terminal:
