Bug ID: 524172
Summary: Network Manager tray menu Hotspot button crashes
unless there is an existing "WiFi (shared)"
configuration
Classification: Plasma
Product: plasmashell
Version First 6.7.4
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Networks widget
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
DESCRIPTION
I must admit the title sounds a little weird but hear me out. I've been puzzled
for two days for being unable to turn on the the WiFi Hotspot via the tray icon
of network manager. plasmashell crashes after clicking on this button (after a
minimal delay, 1s approx?). journal logs a bad_alloc from plasmashell at the
same time, all the times it fails.
There is this weird way of circumventing the problem: first, I created a
shareable network profile in the settings menu as described in
https://discuss.kde.org/t/how-to-set-ssid-password-for-hotspot-in-networkmanager/4414/2
(I went with the defaults, no password). Now you can ignore the created
network. Then the "Hotspot" button becomes responsive and the password popup
appears, lets you type one and opens the WiFi network. You can also remove the
first shareable network profile from settings, and the hotspot button will keep
functioning. Until next reboot. IDK why.
STEPS TO REPRODUCE
1. Open network tray menu icon.
2. Click on Hotspot
3. See status "Waiting for authorization" for a little, then the menu
disappears (plasmashell seems to reload from a crash, as the full toolbar may
seem to reload).
4. See journal.
OBSERVED RESULT
plasmashell crashes and coredumps. No Hotspot is started.
I have the relevant journal (journal -f) and the auto coredump gdb backtrace,
but I don't know if the latter has all the symbols you may need. It did
download some files.

ADDITIONAL INFORMATION
xref report (by me)
https://discuss.cachyos.org/t/networkmanager-kde-plasma-hotspot-cant-be-enabled-bad-alloc-in-journal/33990/2
I have one wired connection and a bunch of previously used WiFi networks in
System Settings > WiFi & Internet > WiFi & Networking. And the shared network
profile when I create it.
I've tried to follow
https://community.kde.org/index.php?title=Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
as much as I could, although I admit I was unable to attach gdb to the existing
plasmashell process / a new plasmashell process started from gdb and get to the
crash. That's why I'm reporting the coredump readback.
I'm interested in debugging further and/or contributing a fix (although I
probably won't stick around for medium/long term). The problem appears to be in
a QKeychain string concatenation, and given the asymmetry of the issue when
other networking configuration is present or not, I have the biased opinion
that the problem is handling the configuration. I don't have a clue thou. I've
provided ~/.config/plasma-nm but I don't know of any other files of interest.
Please, let me know of next steps than can be of help to hunt down the issue.
