Ubuntu Touch App: "Error opening shm"

Question

I am developing an app for Ubuntu Touch, sometimes it crashes with:

t_shm() at lttng-ust-comm.c:886)
libust[4253/4256]: Error: Error opening shm /lttng-ust-wait-5-32011 (in get_wait_shm() at lttng-ust-comm.c:886)
libust[4253/4255]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:886)
libust[4253/4255]: Error: Error opening shm /lttng-ust-wait-5 (in get_wait_shm() at lttng-ust-comm.c:886)
UbuntuWindow - regular geometry
UbuntuWindow::handleSurfaceFocusChange(focused=true)
UbuntuWindow::handleSurfaceResize(width=1200, height=1862)
UbuntuClipboard - Got invalid serialized mime data. Ignoring it.
UbuntuWindow::handleSurfaceFocusChange(focused=false)
UbuntuWindow::handleSurfaceFocusChange(focused=true)
UbuntuClipboard - Got invalid serialized mime data. Ignoring it.
UbuntuWindow::handleSurfaceFocusChange(focused=false)
UbuntuWindow::handleSurfaceFocusChange(focused=true)
UbuntuWindow::handleSurfaceFocusChange(focused=false)

I have no idea what could that mean or where to even start debugging. Apparently this error affects some other apps, but I couldn't google anything useful. Can you give me some pointers about what could that mean and where can I start looking for an answer?

EDIT:It works very well on desktop, the problem is only on the device. (Nexus 7, Ubuntu Touch Utopic)

This is a platform error, it isn't a bug in your app. See the upstream bug on Launchpad.
