Code: # apt-get install libthumbnailer0 I'll add it to the meecolay package no, it's not of icon-s-status-unknown. You need to preload some lib in /opt/qtm12/lib/. this is the problem Code: (/opt/qtm12/plugins/mediaservice/libqgstengine.so: undefined symbol: _ZN14QCameraControl16staticMetaObjectE)" the error is not always the last line
# apt-get install libthumbnailer0
(/opt/qtm12/plugins/mediaservice/libqgstengine.so: undefined symbol: _ZN14QCameraControl16staticMetaObjectE)"
this need to preload libQtMultimediaKit.so
