After the latest (today) rounds of SID level dist-upgrades spacefm refuses to load or start with this error from terminal
spacefm: symbol lookup error: /usr/lib/x86_64-linux-gnu/libutvideo.so.15: undefined symbol: fdLogSock
I have initiated a bug report with debian and the spacefm maintainer (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=785273)
An update to libutvideo15 just came through SID that resolved this issue
