Caught signal: SIGSEGV

[Fritigern]

Please provide the following information

qBittorrent version and Operating System

qBittorrent : 4.1.5.99-201903251247-6693-8f6c305-ubuntu18.10.1 (Tildes replaced by dashes to prevent strikethrough on text)
OS : Kubuntu 18.10

If on linux, libtorrent and Qt version

libtorrent-rasterbar9 : 1.1.11+git20181119.25a1f12991+patched-configure-1ppa1~18.10
Qt : 5.11.1+dfsg-7ubuntu3

What is the problem

qBittorrent closes with SIGSEV, sometimes after a while, sometimes almost immediately. This started a couple of updates ago but I don't remember exactly when.

What is the expected behavior

Well, I kinda expect qBittorrent to remain open and stuff 😆

Steps to reproduce

In the case of my system, start qBittorrent with several torrents in the queue, some paused, some seeding and some downloading.
After several seconds to minutes, qBittorrent will close itself.

Extra info(if any)

Here's the console output. I hope it's useful:

$ qbittorrent

For those who can't follow the instructions in the comment above because the UI crashes immediately, edit ~/.config/qBittorrent/qBittorrent.conf and change DownloadTrackerFavicon to false.
