Bug Description

U1db-qt runs out of memory when creating a database in a directory that doesn't exist. That makes little sense in context of click apps, who's .config/<package name!> doesn't not exist by default.

I.e. if I indicate I want a database in /home/phablet/.config/com.ubuntu.telegram/settings.u1db, I believe u1db-qt should do something along mkdir -p. You may, or may not, agree with me on that part. But it shouldn't fail with out of memory regardless.

u1db: Failed to open /home/phablet/.config/com.ubuntu.telegram/settings.u1db: out of memory Error opening database
file:///opt/click.ubuntu.com/com.ubuntu.telegram/0.8.12.73/telegram.qml:311: TypeError: Cannot read property 'phoneNumber' of undefined // because the db doesn't exist

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?
