Panel crashes when Telegram started
Hi
I experience strange issue with Xfce4-4.18.0. xfce4-panel starts and works fine until I try starting Telegram client. After that panel immediately crashes on segfault.
I tried rebuilding xfce4-panel with debug info (I am under Gentoo). However, the issue happens only inside 3d-party libs. See below.
