Descending Sort Causes Crashes for Certain Metadata

[navy1978]

We’re encountering an unusual issue that occurs specifically with certain datasets, such as the Final Burn Neo ROM set. This issue affects all descending sort filters, except for filename and sort name, which remain unaffected.

When attempting to perform a descending sort, the system crashes with a segmentation fault. Below is the GDB backtrace:

`(gdb) run

The issue appears to be related to the "getChildrenListToDisplay" method in the "FileData.cpp" class.
