I tried to use the new 'Deploy' wizard for a .pro file based project. However, the wizard doesn't accept my control file (see attached file):

The project is missing some information important to publishing:
- You have not set an icon for the package manager.
Publishing failed: Missing project information.

However, I have added an XB-Maemo-Icon-26 entry to the control file, like http://maemo.org/development/documentation/manuals/4-0-x/creating_a_debian_package/ suggests.

It seems the logic in QtCreator cannot really handle multi-line entries: MaemoTemplatesManager::controlFileFieldValue only searches for the value of the entry up to the next newline, while the encoded icon will usually go over multiple files.
