Some icons are not visible

[Wolfgang Eder]

Bought a bq phone with Ubuntu. First thing it does was updating Apps and the OS to Ubuntu Utopic Unicorn (development branch) - armhf (20150410-232623). Build number 21.

Icons are missing at the apps scope as well as in the launcher see: https://plus.google.com/113135226934524593062/posts/Rc7eYNHdntM

I can't remember if the icons were visible prior to the OS Update.

The issue in Apps is likely bug #1430828, it's going to be resolved in the first vivid-based OTA.

The launcher issue, however, is new to me, can you identify what app is it? If you long-press, unpin it and pin it again, is the icon back?

[Wolfgang Eder (wolfgang-eder)]

Every app which has no icon in the app scope has no icon in the launcher when launched. In this picture it was the Telegram app, but every other one has the same behaviour.
Unpining and repining it again has no effect.
The solution was to deinstall the app and reinstall it. Then the icon is back.

I noticed, that at the notification of e.g. an incoming Telegram message, the little icon was also missing.

Sorry about that, no one else ever reported such an issue... Do you still have some of the items with missing icons or have you reinstalled all of them? If you could please look in ~/.cache/upstart/unity8.log or unity8-dash.log (and the .*.gz ones too, they're the older ones) for relevant image loading error messages, that could help.

If you have one that's still missing an icon, please look in ~/.local/share/applications, in the relevant .desktop file, for the Icon= line, and see if the referenced file exists and is a valid icon file.

I have reinstalled all of them, now every icon is there.

Error in the unity8.log file:

** (process:2298): WARNING **: Unable to get pids for 'unity8-dash' to send signal 19
ApplicationController::pauseApplication FAILED to pause appId= "unity8-dash"

The same Error occurs multiple times in older unit8.log files (unit8.gz files) with different process number

In unity8-dash.log:
[...]

Don't know if this helps.
