Details

Description: qbittorrent dumps its core when run. If I downgrade to the previous versions of qbittorrent and libtorrent-rasterbar everything opens fine. Trying the newest libtorrent + prev version of qbittorrent or the opposite does not work as the current qbittorrent relies on libtorrent-rasterbar.so.9 while the previous version relied on /usr/lib/libtorrent-rasterbar.so.8

Steps to reproduce:
Update to latest versions (qbittorrent 3.3.4-2 and libtorrent-rasterbar 1:1.1-2 . Run qbittorrent in terminal and it will dump:

Setting "IPFilter\Enabled=false" in ~/.config/qBittorrent/qBittorrent.conf solves the problem

Forum Post: https://bbs.archlinux.org/viewtopic.php?pid=1637089#p1637089

It's related with IPFilter, same happens with Deluge, having IPFilter enabled breaks the application.

Adding a link to the relevant bug in qbittorrent's bugtracker:

Testing and bug is still present in QBittorrent 3.4.5
Edit: Forgot to add that setting IPFilters to false in the qbittorrent config file ~/.config/qBittorrent/qBittorrent.conf will cause it not to crash, it will launch normally.

hello all
If you want to open IPFilters please try to follow suit

I have posted a patch and new PKGBUILD for libtorrent-rasterbar on this  bug 49861  which has the fix to libtorrent-rasterbar. Please see my post there. Fixing that will fix both that bug and this one.
