Bug ID: 503420
Summary: "QLayout: Cannot add a null widget to QHBoxLayout/"
error when invoking konsole + ssh at a shell prompt
Classification: Applications
Product: konsole
Version: 25.04.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org
Reporter: jfischer_5...@yahoo.com
Target Milestone: ---
SUMMARY
When I spawn a new konsole instance via a shell prompt, and the konsole command
line uses the `-e` option to invoke an SSH command line, the newly created
konsole process emits the following diagnostic message:
QLayout: Cannot add a null widget to QHBoxLayout/
STEPS TO REPRODUCE
1. Open any command shell window, e.g., xterm, konsole
2. At the shell prompt, type a command line that spawns a new konsole process,
and uses the `-e` option to invoke an SSH command line, such as:
/usr/bin/konsole -e /usr/bin/ssh -A -X -i ~/.ssh/id_ed25519 -p 22
pi@192.168.1.3
[Note 1. In this example, the SSH command performs a remote login as user 'pi'
on a Raspberry Pi whose IPv4 address is 192.168.1.3. --end note]
OBSERVED RESULT
$ /usr/bin/konsole -e /usr/bin/ssh -A -X -i ~/.ssh/id_ed25519 -p 22
pi@192.168.1.3
QLayout: Cannot add a null widget to QHBoxLayout/
QThreadStorage: Thread 0x563588e32bc0 exited after QThreadStorage 9 destroyed
A new konsole window opens, the SSH command line runs and successfully logs in
as user 'pi' on the remote host. I can now use the new konsole window to run
commands on the remote host.
EXPECTED RESULT
The same as above, but without the Qt diagnostic message
QLayout: Cannot add a null widget to QHBoxLayout/
[Note 1. I've filed a separate but report regarding the second Qt diagnostic
message,
QThreadStorage: Thread 0x563588e32bc0 exited after QThreadStorage 9 destroyed
--end note]
