Qterminal processes vanish with `labwc -S`

[stefonarch]

It's a tricky one. I noticed for some months that sometimes my dropdown terminal "refreshes" (all open tabs are gone, bookmarks pane is closed).

Now I discovered how to trigger it. labwc -S app opens a nested labwc session with an application which closes itself when the application window is closed, and here it closes also every qterminal window that may be open, including the dropdown one.

Key points:

• happens only on my user (more precisely: with my rc.xml, see comment)
• happens only with qterminal (konsole, qterm are fine)
• no message when I launch qterminal from another terminal (just "terminated")
• independent from compositor running (niri, labwc)
• clean .bashrc and qterminal configurations makes no difference
• no coredump
• running just labwc and closing the window with the nested session is no problem but cltr+c will close also the terminal instead of the nested session only
• starting wayfire is fine when exiting it with ctrl+c

Expected Behavior

No way that a terminal window just vanishes

Current Behavior

they do

Possible Solution

Find the ghost in my system (or in qterminal)

Steps to Reproduce (for bugs)

1. Open 2 or more qterminal windows
2. Run labwc -S lxqt-about in one
3. Close lxqt-about or use cltr+c to stop the process
4. All windows are closed

Since it only happens with labwc -S, I'm not sure we can do anything with it here.

And I can't reproduce it with labwc -C /tmp -S fpad.

[stefonarch]

Me neither :) It looks it's my labwc configuration, will look into it

[stefonarch]

There were some deprecated keys in the config, I fixed them all but it's still happening.
But in any way terminating by ctrl+c any process should never terminate all qterminal processes.

Last findings:

• labwc -C /usr/local/share/doc/labwc/ -S lxqt-about is safe, qterminal not vanishes
• labwc -c /usr/local/share/doc/labwc/rc.xml : all qterminal processes exit when labwc exits (by root menu)

I think this is rather a question about labwc or something in your system. I can't reproduce it with rc.xml provided by labwc either. Perhaps somewhere you have a command like killall qterminal, or who knows?

[stefonarch]

As I said, I cannot reproduce it either on my testuser. But it's a fact that not only this labwc thing triggers it but also something else, as maybe once a week my tabs are lost and I need to hit F12 twice.
Other processes I can terminate with ctrl+c without qterminal closing.

[tsujan]

I didn't say that it didn't happen to you; why should I?! I mean searching its cause in qterminal may be futile because, first, it's about labwc -S and, second, I couldn't reproduce it here by following any suggestion you made.

[stefonarch]

Where the reason is is hard to tell, fact is that it happens to me only in qterminal. Asked also on the labwc side, if they have an idea.

[tsujan]

fact is that it happens to me only in qterminal

My two cents:

Reading your sentence in this way may be a faster method of ruling out improbable causes: "… fact is that it happens to me only in qterminal" ;)
