Can you get a backtrace form kamoso? Either start it from cli with kamaso
, see if the konsole prints something useful on the crash, or start it with gdb kamoso
then type run
, on crash type'bt
and hit enter
a few times to get some backtrace.
Is this a build-in webcam? USB webcam?
There also is a new upstream release, just build, so try and see if that fixes any:
sudo pacman -U http://kaosx.tk/repo/build/kamoso-3.2.4-1-x86_64.pkg.tar.xz
