Current Behavior

When I open Albert and type the trigger query for the Bitwarden plugin ("bw"), Albert immediately freezes and becomes completely unresponsive. The application window remains visible but cannot be interacted with, and I cannot type further queries. The debug log stops just after the "bw" query is processed and reports "Busy wait on query". I have to manually terminate the Albert process (e.g., via pkill or a system monitor), which sometimes results in a core dump being reported by the system journal. No specific critical errors are logged by Albert itself at the moment of the freeze.

Expected Behavior

When I type the trigger query "bw", Albert should execute the Bitwarden plugin, display search results from my Bitwarden vault, and remain responsive for further interaction.

Anything else?

Albert Version Details:

    Albert version: 0.27.8

    Build date: Oct 27 2017 00:00:00

    Qt version: 6.8.2

    Operating System: Nobara Linux 41 (KDE Plasma)

    Kernel Version: 6.14.2-201.nobara.fc41.x86_64

    Platform: wayland

Bitwarden Plugin: The plugin is installed at /usr/share/albert/python/plugins/bitwarden. Its __init__.py file declares md_iid = "3.0".

rbw executable: The required rbw command-line tool is installed on my system and works correctly when run directly in a standard terminal (e.g., rbw list returns results).

Debug Log Observations: The debug log shows a significant delay (7160 ms) associated with query albertlauncher/albert#3 'bw ' immediately preceding the manual termination, alongside a "Busy wait on query" warning, strongly suggesting a hang or deadlock during plugin execution.

Troubleshooting: Disabling the Bitwarden plugin prevents the freeze. Re-enabling it causes the freeze to recur. There is no shadowed plugin in ~/.local/share/albert/python/plugins/.

@ovitor @daviddeadly any ideas?

I have experienced exactly the same as mg-dev25. Very similar output of no errors, just blank during the freeze. For testing, I am running QT_LOGGING_RULES=albert*=true albert --platform xcb to launch.

Tonight I had a thought to check the Albert Query handler trigger, and it seems like the issue might be connected to it.

I replaced the default trigger in the Settings Query tab with just bw without the space and I was able to run one query and copy password to clipboard. I triggered Albert via hotkey a second time and only typed bw and it froze immediately.

After reloading Albert, I tried again, and it worked but again only the first query. Interestingly, it would also freeze if I did not perform an action on the result, but just backspace/deleted back to the original bw - it would freeze as soon as I got to the w.

I tried the python docker plugin with and without a space and it didn't have this issue. I'm not so much a programmer as a user, but I can help test further if needed.

My env is:
Manjaro x64
KDE Plasma 6.3.4
X11
Fresh recompile of Albert 0.27.8, clearing .config/albert before testing
Qt 6.9.0
Kernel 6.12.21-4
