Couldn't simplify path error on Linux startup

Hello! Downloading and compiling a fresh install on Linux (Ubuntu 22.04 LTS/Xfce) gives an error on startup, though this error is ignored and everything else seems to start up ok:

./cap32

ERROR   src/gui/src/CapriceLoadSave.cpp:286 - Couldn't simplify path '/home/dave/Development/cpc/caprice32/disk/': No such file or directory

Creating the disk directory at the top level (this is not created by the makefile btw) ensures everything is ticketyboo and no error occurs on startup.
