My KDE desktop crashed every time the system starts, after installing a batch of packages updates last night.

After checking journal command I found this piece of error message among numerous logs:

"4月" = "April"

libFcitx5Qt6DBusAddons.so.5.1.5 has caused mutiple segmentation faults, which finally makes KDE desktop failed to start.
(Well, actually it failed to start its 99% of functionality and I traced the problem with the only 1% of functionality that only several non-native-windowed applications like edge & android studio can work normally---nothing else left on the screen---or I will never made it to report this issue here)

It should be a error by fcitx's some (qt6-support?) plugins.
After uninstalling fcitx5 main package the fault is not removed;
After uninstalling all fcitx-related packages (all installed deb packages with "fctix" in its name) the fault is removed, and my desktop works well again.

That's all.
Finally plz check this bug ASAP because it may be relating a fault published into the STABLE branch!

.....cannot imagine how can I survive in my linux for the next several weeks/mounths without a Chinese IM.

Is there anyway to add compile time checks so pkg maintainers don't accidentally push out useless library combinations?
