Description hrwy 2019-05-01 21:17:55 UTC 
Problem: Falkon after ~ 5 min stops working with clipboard
I see these messages in terminal: "QXcbClipboard::setMimeData: Cannot set X11 selection owner"

Maybe solving of the problem:
1) Qt upgrade
2) Application upgrade
3) installation if it didn't installed: xsel / xclip
4) In Vim: `set clipboard=unnamedplus`, which makes the anonymous register the Xorg clipboard
My problem solving:
5) sudo mv /usr/bin/xclip /usr/bin/xclip.disabled reboot... X
6) brew install xclip #(from LinuxBrew) reboot... X; restored xclip, renamed xsel reboot - NOTHING HELPED

Other applications with problem:
Qt 5.6.0+SecureCRT 8.5.2
Qt 5.5.1+qBittorrent3.3.13, 64 bit.
Qt < 5.9.11+Telegram 1.6.2 (but newer versions had resolved issue)
somebode reported problems after closing LyX
Qt+some terminal+Vim+Klipper(clipboard history not empty)
Qt5+Pyperclip(https://www.reddit.com/r/learnpython/comments/8v2d74/copied_content_via_pyperclip_does_not_persist_in/)

Would you give me a clue how to turn in my Falkon debugging. What would I need to do? Compile sources of Current branch (it like my Falkon from ppa:lubuntu-dev/falkon-daily have last changes), but I never use cmake "with debugging symbols" parameter, I only knows how add symbols in qmake…

(In reply to hrwy from comment #2)

"-DCMAKE_BUILD_TYPE=Debug"

But it probably won't help you because this looks like regression of  QTBUG-28398, see https://bugreports.qt.io/browse/QTCREATORBUG-8476?focusedCommentId=193125&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-193125

Thanks. I will start to using compiled falkon, with debugging, to see what happens.

Any update?
