Bug Description

After the upgrade to qt 5.2, filemanager fails to load it's UI. All tests fails, and the app fails to run on the device. The traceback from the desktop is:

qmlscene ../../ubuntu-filemanager-app.qml

So is this on desktop only?

It seems to work ok on mako, and also all the tests are passing on images: http://ci.ubuntu.com/smokeng/trusty/touch/mako/245:20140318.2:20140304/7250/

That's an odd way to run the app.

Did you build a full .deb, installed it and run it "normally" e.g.
from /usr/bin/ubuntu-filemanager-app ?!

Well, ubuntu-mobile-icons on my machine does not have such file.

I don't see anything "Qt5.2" failing here so far.

these seem qml / programming errors, maybe cause by previous warnings.

Let's not put assumptions into the title of the bug report =)

* Right the "arrow" icon is suppose to come from local ./icons/, it is included in the package but not loaded.

* ubuntu-filemanager-app.qml:113: ReferenceError: settingsPage is not defined, indeed I don't see were settingsPage is defined. Are there uncommitted / missing files?

* ubuntu-filemanager-app.qml:93: TypeError: Cannot read property 'opened' of null: did the toolbar api changed? cause that object appears to be null now, and thus one can't read any of its properties anymore.

-r131 does run against Qt5.2 fine, thus it's not a "qt5.2 problem". We should investigate r132 as it seems to introduce a lot of changes, which might be incomplete based on above comments.

Yes, r132 introduced many changes and seems to be the cause of the breakage.

I had jenkins run r131 with an updated cmake and it seems fine.

Sorry for blaming qt5.2, that wasn't my intent :-)

@Timo, the version on the images is old (r99). I was hoping to update it and realized several things were broken and a new version couldn't be landed.

Fix committed into lp:ubuntu-filemanager-app at revision 141, scheduled for release in ubuntu-filemanager-app, milestone alpha-1
