Avoid warning, pointer target in assignment differ in signedness
During build stage (with the latest devel release), I get this message:
xfdesktop-file-icon-manager.c:3694:22: warning: pointer targets in assignment from 'gchar *' {aka 'char *'} to 'guchar *' {aka 'unsigned char *'} differ in signedness [-Wpointer-sign]
3694 | filename = g_strdup(_("Untitled document"));
| ^
Patch fixes this issue.
