What steps will reproduce the problem?
1. Install chromium-browser on ubuntu xenial amd64 (probably does not really matter which version)
2. Edit /etc/chromium-browser/default to include CHROMIUM_FLAGS="--incognito" to make chromium default to incognito mode.
3. Install an app from chrome.google.com (possible from extensions menu, non incognito mode)
4. In chromium app overview right click on that app and choose "Create Link" then tick both Desktop and Apps-menu.
5. Launch that .desktop file (which chromium closed before)
6. Launch chromium-browser from command line with that Exec=... command from the .desktop file like "/usr/bin/chromium-browser --profile-directory=Default --app-id=<app id in here>"

What is the expected result?
Chromium should either start the app (but it can't in incognito mode), or at least display a warning popup or console message about the reason why it won't create any window. (Something like app not found, or refusing to launch app in incognito mode, or both?).

What happens instead of that?
Chromium just sits there, doing nothing and making the impression that something is broken (as nothing happens, not even a warning).

(By the way havent found out where a link in Apps-menu should have landed, can just find that .desktop file, but I guess thats another issue.)
