panic: runtime error: index out of range [0] with length 0

I just installed this (first time user) and am seeing a panic (logs below).

Version b8ae7b68 (current master), connecting to a single tracker. I noticed this by dropping into the IRC channel manually and seeing my configured user leaving and re-entering (running in a Docker container with restart: unless-stopped).

Basically this is the example configs without the exclusion on HEVC. The crash clearly looks related to the bencode portion. Setting both bencode options for my single tracker to false appears to avoid the issue, so far...
