Comment 2 for bug 1962372

So I recently had to compile Thunar 4.19.2 for Xubuntu 22.04, and saw this issue still exists there, so dug into it again. And this time was able to come up with a small patch to Thunar 4.19.2 that fix the issue (probably not the best fix, since I don't actually know what I'm doing in C/C++, but it seems to do the job so should at least point in the right direction).

This would ideally be brought to upstream Thunar/Xfce devs' attention at https://gitlab.xfce.org/xfce/thunar/-/issues But I was unsuccessful in looking into registering an account there. So I'm posting the patch below. Could someone please notify Thunar/Xfce devs about this bug & the below tentative patch? Thanks :)
