I couldn't find a topic mentioning whether UDP trackers are supported or not, but here is a crash I got when, after adding a torrent with only a UDP tracker, I tried to select it in the list and click "Change Tracker", because there was no tracker in the box above the list. This is with 2.1rc1.

Code: Select all
