Description of problem: Running the copyq program doesn't start the daemon and repeatedly prints "QSystemTrayIcon::setVisible: No Icon set". Version-Release number of selected component (if applicable): copyq-2.5.0-1.fc23.x86_64 How reproducible: Everytime. Steps to Reproduce: 1. Install minimum Fedora 23 installation from netinstall medium (without prepared KDE environment). 2. Install i3, gnome-terminal. 3. Install gpaste. 4. Run $ qopyq CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemdata.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemencrypted.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemfakevim.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemimage.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemnotes.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemsync.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemtags.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemtext.so CopyQ Loading plugin: /usr/lib64/copyq/plugins/libitemweb.so QSystemTrayIcon::setVisible: No Icon set QSystemTrayIcon::setVisible: No Icon set QSystemTrayIcon::setVisible: No Icon set QSystemTrayIcon::setVisible: No Icon set QSystemTrayIcon::setVisible: No Icon set QSystemTrayIcon::setVisible: No Icon set [...SNIP...] Actual results: copyq starts the daemon, the applet in systray and runs normally. Expected results: The last message in the above output is quickly repeated infinitely often. Additional info: I've debugged it without debugging symbols. If debug with symbols would help please tell me I'll attach it. It seems that it's stuck in some infinite loop (see below please). There's probably some missing dependency. (I already had a problem with Dolphin for which I had to manually install kf5-frameworkintegration to make any icons appear (folders, files). It didn't go into infinite loop though.) $ gdb copyq Reading symbols from copyq...Reading symbols from /home/woky/copyq...(no debugging symbols found)...done. (no debugging symbols found)...done.

I am not able to reproduce the problem, and we're now on 2.6.1 - so not sure what was happening on your particular installation. If you're still having issues, please document and I will consult upstream.
I don't know about the OP but this bug stems from using XDG_CURRENT_DESKTOP=kde in my case. If I use that export then CopyQ won't show system tray icon. If I don't use that export then none of the Qt file browsers will show icon. Whole Qt apps ecosystem seems to be affected by this if you were to search "QSystemTrayIcon::setVisible: No Icon set" If you want to try to replicate this then follow the steps. dnf install i3 i3status set XDG_CURRENT_DESKTOP=kde in ~/.bashrc login into i3 then run CopyQ
Well, wouldn't that indicate it's not an issue with copyq? I'm not using i3 and am not experiencing any issues with either lxqt or plasma - both using kwin.
I would think so.
Good catch Sudhir. I've put "export XDG_CURRENT_DESKTOP=kde" some time ago in my ~/.xinitrc. I did it because the Dolphin (KDE5 already) wouldn't show any icons without it, not even files. I googled it as a possible fix and I didn't care about details. I removed the Dolphin after trying it for a while and forgot about the variable. Unsetting XDG_CURRENT_DESKTOP fixed the problem for me. Googling "QSystemTrayIcon::setVisible: No Icon set" brings lots problems which are seemingly unrelated to each other and mostly innocent. However, CopyQ was the only Qt/KDE program I run that turned into infinite loop with this variable set. I don't think it's NOTABUG but it probably belongs to upstream's bugtracker.
(In reply to Tomáš Nechutný from comment #5) I don't think it's NOTABUG but it probably belongs to > upstream's bugtracker. Thanks for the feedback. I'm not experiencing the issue, so if you feel strongly about it, feel free to report it upstream. Would be more efficient than me relaying messages back and forth.
