Comment 1 Mauro Carvalho Chehab 2016-06-24 00:44:35 UTC 
Looking from the trace, I suspect that it has something to do with libVLC. Maybe you had some upgrades at VLC side.

Yet, we're not supporting Kaffeine 1.3 upstream anymore. There are simply too many changes from it to Kaffeine 2.x, including the migration to Qt5, and several fixes at playlist (where the code hanged).

Please either report this bug to Mageia or upgrade to the latest version (2.0.3) or to the git one (I'm about to release a 2.0.4 from the current git tree - I'm just giving some time to i18n people for translations).

If the bug happens with Kaffeine 2.0.3(or -git), please re-open, with Kaffeine logs (those are enabled with the new --debug option).
