Here's what I see with pcmanfm from the x86 11.x repo: $ tce-load -i pcmanfm
...
gtk-query-immodules-2.0: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
...
$ pcmanfm
pcmanfm: error while loading shared libraries: libpcre.so.0: cannot open shared object file: No such file or directory
If I then add pcre as a dep of gtk2, pcmanfm works without the need for gsettings.
gtk2 dep file adjusted.
