Using Language Tool to load Chinese, starting Slicer results in a crash. However, if Japanese is loaded, the startup is normal.

In summary, the problem is caused by incorrect translation of `Segmentations` module: it is translated as `Segmentation`, which is the exact same word that is used as module category name.

We fixed the crash in the Slicer Preview Release so that now a warning is logged instead of crash when a module name matches a module category name. However, you still need to modify the Chinese translation to not use the same string as both a module name and a module category name.
