Just got hit by this problem, whenever I tried to deploy my application:
11:06:04: Package created. 11:06:04: Installing package to sysroot ... Package 'untitled' installed. 11:06:04: Preparing SFTP connection... 11:06:04: Starting upload... 11:06:04: Failed to upload package: Failure 11:06:04: Deploy step failed. Error while building project untitled (target: Harmattan) When executing build step 'Deploy Debian package via SFTP upload'
And a notification warning about the little remaining data storage appeared on the device, which I wrongly ignored at first. The problem occurs because QtCreator tries to copy the debian packate to /tmp on the device, N9 for me, and it fails if the space is full. I managed to fill my /tmp partition (which is just 4Mb btw..) by testing some big application. Solution is, ssh to your device, check if you /tmp is full (df -h) and delete any .deb file left there by QtCreator.

UPDATE: This is supposed to be fixed on QtCreator 2.5 according to https://bugreports.qt-project.org/browse/QTCREATORBUG-6859
