Description Nick Leverton 2012-12-12 10:00:26 UTC 
Since upgrading to 4.9.90, Skype's system tray icon does not show up.  In its place there is a blank white sheet icon with folded corner. Up to 4.9.4 Skype's icon was correctly shown (it normally reflects the online status plus an indicator for outstanding messages).

I am on skype 4.1.0.20.  I appreciate skype is closed source but we require it for work, so is it possible to debug what is happening here please ?

Reproducible: Always

Comment 1 Francesco Cecconi 2012-12-13 10:39:06 UTC 
I can't reproduce this issue with version 4.9.90 git 13/12/2012.
Comment 2 Alexei Ivanov 2012-12-13 18:32:48 UTC 
I have the same problem after upgrading to 4.9.90 Beta 2.
Skype v.4.1.0.20.
Comment 3 Christian González 2012-12-15 13:50:35 UTC 
Same thing happens with others pure-Qt apps, like KeePassX and HackTray. Oddly enough, others pure-Qt apps like qBittorrent shows its icons correctly.

I'm using 4.9.90 from kubuntu-ppa-beta-quantal.
Comment 4 Francesco Cecconi 2012-12-15 17:56:14 UTC 
Well, this is a kubuntu-related issue and Harald Sitter is working on it.

Comment 6 Admc 2012-12-16 10:50:44 UTC 
All apps in ubuntu must support libindicator (aka ayatana) system tray icons, because unity doesn't show legacy system tray icons. Fortunately KDE support both ayatana and legacy system tray icons. In KDE 4.10 systemtray plasmoid was rewritten which caused a regression. There's a problem which appears when sni-qt package is installed. Some qt apps are using sni-qt to provide ayatana consistent system tray entries. Those apps' system tray icons are just displaying generic "missing icon" instead of normal system tray icons (see screenshot). Temporary workaround is to uninstall sni-qt package.

KSNI: fix IconThemePath support

IconThemePath is used by a Canonical Patch to enable all Qt apps using
QSystemTrayIcon to transparently provide a SNI with icons exported into
a temporary path. Hence the lack of support breaks icons for all Qt apps
on Ubuntu.

Fix:
- in the dataengine export IconThemePath
- in the systray protocol pick up the value and forward to QML
- in QML set the themePath accordingly on the IconItem
  (requires changes in runtime)
