I have upgraded from Ubuntu 18.10 to 19.04 by do-release-upgrade command and I have exactry the same problem.
About a second after login to desktop, attached System Error dialog box popped out every time, but no detailed information was shown when clicked "Report Problem". By observing syslog messages by journalctl -f, the following error messages ware shown every time: 4月 24 20:23:44 deepk gnome-shell[15196]: [AppIndicatorSupport-FATAL] unable to update overlay icon 4月 24 20:23:44 deepk gnome-shell[15196]: [AppIndicatorSupport-FATAL] unable to update overlay icon 4月 24 20:23:50 deepk gnome-software[16378]: Failed to find one package for nvvp.desktop, /usr/share/applications/nvvp.desktop, [0] 4月 24 20:23:50 deepk gnome-software[16378]: Failed to load snap icon: local snap has no icon 4月 24 20:23:50 deepk gnome-software[16378]: Failed to load snap icon: local snap has no icon 4月 24 20:23:50 deepk gnome-software[16378]: Failed to load snap icon: local snap has no icon 4月 24 20:23:51 deepk gnome-software[16378]: hiding category audio-video featured applications: found only 0 to show, need at least 9 4月 24 20:23:52 deepk gnome-software[16378]: Failed to load snap icon: local snap has no icon ** Attachment added: "SystemError_Screen.png" https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-appindicator/+bug/1825623/+attachment/5258584/+files/SystemError_Screen.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell-extension-appindicator in Ubuntu. https://bugs.launchpad.net/bugs/1825623 Title: [AppIndicatorSupport-FATAL] unable to update overlay icon Status in gnome-shell-extension-appindicator package in Ubuntu: New Bug description: After startup or login, An error occurs that just states cancel or report... but does not open a detail dialog Error messages in the syslog: ...
