Crash in "canvas" qml example during startup

[Johnny Jazeix]

hi,
for the logs, in GCompris, we use "normal" qDebug() and they are well
printed in the logcat.

Regarding the last SIGSEGV, sometimes, I had to run it multiple times to
have a stacktrace. Laybe it can help having more info.

Sorry I don't have more clues.

Cheers,

Johnny
