This seems to be triggered specifically by the fact that camera-app is fullscreen (so possibly also related to bug 1470780 as Albert suggests, since the media player is also fullscreen, however I haven't been able to reproduce that one myself yet). After modifying camera-app to launch in non-fullscreen mode the bug doesn't get triggered.
Attaching GDB to maliit-server shows that it seems to be stuck waiting for a mutex, but without enough debugging info to show where that call originated: #0 0xb6033d44 in __libc_do_syscall () from /lib/arm-linux-gnueabihf/libpthread.so.0 #1 0xb602f6b0 in pthread_cond_wait@@GLIBC_2.4 () from /lib/arm-linux-gnueabihf/libpthread.so.0 #2 0xb68ba0d8 in QWaitCondition::wait(QMutex*, unsigned long) () from /usr/lib/arm-linux-gnueabihf/libQt5Core.so.5 #3 0xb64cf9ee in ??
