Comment 2 for bug 1390166

I'm running into this problem too. It's fairly critical as my app relies on U1DB and crashes on startup as a result.

I get the following output when running my app on the Ubuntu emulator:

Sdk-Launcher> Application started: 17278
u1db: Failed to open /home/phablet/.local/share/org.thecosmicfrog.dublinwheels/dublinwheels.u1db: out of memory Error opening database
QIODevice::read: device not open
tile request error "Problem with tile image"
UbuntuWindow::handleSurfaceFocusChange(focused=true)
UbuntuWindow::handleSurfaceResize(width=480, height=770)
QIODevice::write: device not open
Sdk-Launcher> Received a failed event
Sdk-Launcher> The Application exited, cleaning up
Sdk-Launcher> Finished

Is there some sort of workaround or alternate form of persistance I should be using?
