[Bug 1793242] [NEW] KDE saves and restores all but Google Chrome in its Desktop saved session

[Stas]

Public bug reported:

For some reason when enabling Restore manually saved session in Desktop
Session Login and Logout settings, and hitting Save Session from the
applications menu - all opened application windows get saved and
restored upon login into the KDE session, except google chrome.

I located the session file ~/.config/ksmserverrc and indeed firefox and
many other applications are there:

$ grep firefox ~/.config/ksmserverrc
program11=firefox
restartCommand11=/usr/bin/firefox,--sm-client-id,10686f70[...]
$ grep gkrellm ~/.config/ksmserverrc
program12=/usr/bin/gkrellm
restartCommand12=/usr/bin/gkrellm,--sm-client-id,10686f70[...]
$ grep chrome ~/.config/ksmserverrc

as you can see chrome is not there.

And no application has been configured to be excluded:

$ grep excludeApps ~/.config/ksmserverrc
excludeApps=

The only unusual thing about chrome, as compared to other applications,
perhaps, is that it appears as many threads in the output of ps(1).

I have it installed as:

$ sudo apt-get install google-chrome-stable
google-chrome-stable is already the newest version (69.0.3497.100-1)

My setup:

lsb_release -rd
