wf-panel crashes with a segmentation fault shortly after launch.

The crash generates a coredump and appears related to GTK/IBus input method integration. The system journal also shows related graphical session and portal instability:

graphical-session.target - Current graphical user session is inactive.
Dependency failed for xdg-desktop-portal.service - Portal service.

coredumpctl info wf-panel reports:

Signal: 11 (SEGV)
Executable: /usr/bin/wf-panel

Relevant loaded modules during crash include:

Module libibus-1.0.so.5
Module im-ibus.so

Testing with the following environment variables may prevent the crash:

GTK_IM_MODULE=none QT_IM_MODULE=none XMODIFIERS= wf-panel

This suggests the crash may involve IBus or GTK input method initialization.

To Reproduce
Start Wayfire session on Fedora 44
Launch wf-panel
Observe panel crash / segmentation fault
Verify with:
coredumpctl info wf-panel
Expected behavior

wf-panel should launch and remain stable without crashing.

Screenshots / Videos / Stacktrace

Relevant coredump information:

PID: 1992 (wf-panel)
Signal: 11 (SEGV)
Command Line: wf-panel
Executable: /usr/bin/wf-panel

Additional logs:

Process 1992 (wf-panel) of user 1000 dumped core.

Potentially relevant modules:

Module libibus-1.0.so.5
Module im-ibus.so
Additional context

Environment:

Fedora 44
Wayfire session
xdg-desktop-portal failures occurring around same time
Clipboard/paste instability also observed during session

Potential workaround:

GTK_IM_MODULE=none QT_IM_MODULE=none XMODIFIERS= wf-panel

May indicate interaction between wf-panel and IBus/GTK IM module loading.

Start by reproducing the Fedora 44 crash with wf-panel and inspect the coredump using coredumpctl info wf-panel, paying attention to the reported IBus and GTK input-method modules. Compare normal startup with GTK_IM_MODULE=none QT_IM_MODULE=none XMODIFIERS= wf-panel; done means wf-panel launches and remains stable without a segmentation fault.
