Crash with certain characters in directory names on FreeBSD

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

A FreeBSD user reported a reproducible crash via IRC.

<ene> I have longstanding problem, currently with darktable 5.2.1 on freebsd 13.5 (amd64). With locale > echo $LC_CTYPE / $LANG / $G_FILENAME_ENCODING

<ene> nb_NO.ISO8859-1 / nb_NO.ISO8859-1 / ISO-8859-1

<ene> darktable segfaults when selecting add to library and the requester goes into a directory containing ø or æ. Curiously å doesn't segfault. I've been working around this for some years by executing "darktable ." in the directory in question, but is there some other solution?

Steps to reproduce

elg!ene[~]> mkdir dtlang
elg!ene[~]> cd dtlang
elg!ene[~/dtlang]> mkdir en to tre fire
elg!ene[~/dtlang]> darktable

** I can select add to library and go to "dtlang" in the file requester fine.

elg!ene[~/dtlang]> mkdir ål
elg!ene[~/dtlang]> darktable

(darktable:30173): GLib-CRITICAL **: 14:36:47.033: g_convert: assertion 'str != NULL' failed

** I can still go to the directory in the file requester

elg!ene[~/dtlang]> mkdir øl
elg!ene[~/dtlang]> darktable

** navigating to dtlang now results in this

Reproduce the crash on FreeBSD 13.5 with the reported nb_NO.ISO8859-1 locale and directory names containing ø or æ, then inspect the linked dtdebug.txt logfile. Trace the file-requester path involved in navigating to the affected directory. Done means selecting Add to Library and opening such directories no longer crashes.
