i'm using async = false

void QmlVlcPlayerProxy::stop() { //use async stop to avoid freeze (on network timeout for example). player().stop( false ); }

[RSATom]

yes, I see. but crush is deep inside libvlc, and even not libvlc itself but in pthread call of some kernel function (if I understand right what is linux-gate.so). It's looks like some compatibility issue between libraries. Did you get this crash on every stop() or time to time?

[pincopallopino]

it's a random crash

[RSATom]

does it still crash?

[pincopallopino]

no, i haven't seen this crash anymore

[RSATom]

then it seems it some OS related issue
