OK I think I found what happens here: WARNING: long App ID encountered: tmpu_5uhy_8
** (process:2551): WARNING **: Unable to get manifest for 'tmpu' package: tmpu does not exist in any database for user phablet ** (process:2551): CRITICAL **: manifest_version: assertion '*manifest != NULL' failed ** (process:2551): CRITICAL **: ubuntu_app_launch_triplet_to_app_id: assertion 'version != NULL' failed ApplicationManager REJECTED connection from app with pid 13154 as desktop_file_hint file not found The random tmp application name sometimes includes underscores, and at some point it randomizes to two underscores, at which point it's assumed that this is an app id and things go haywire. Simple solution: stop the tmp app name from having underscores. Needs investigation: can we be more robust in unity-mir/unity8 here? ** Changed in: qtubuntu (Ubuntu) Status: Confirmed => Invalid ** Also affects: unity-mir Importance: Undecided Status: New ** Also affects: qtmir Importance: Undecided Status: New ** Also affects: unity8 Importance: Undecided Status: New ** Summary changed: - qmlscene crashed while running test_can_launch_multiple_applications + Two underscores in .desktop file name causes assumption that this is an appId and app is rejected. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtubuntu in Ubuntu. https://bugs.launchpad.net/bugs/1329141 Title: Two underscores in .desktop file name causes assumption that this is an appId and app is rejected.
