Took a while to investigate.

The xdg-open app is a shell script, part of xdg-utils. On Slackware 
the file is installed to /usr/bin.

The script offers no support for Trinity. Perusing the script 
indicates a poorly written script rather than anything robust. No 
error-checking or "idiot-proofing" at all. The script provides no 
optional methods of detecting the desktop. The presumed desktops 
are hard-coded and the "generic" functions are poorly written.

On my system anything I try to open wih xdg-open is opened in my 
default browser, Firefox.

I tested in KDE4 and everything works but only because KDE is one 
of the few supported desktops.

I have no idea why GIMP is opened. The user could edit xdg-open and 
add some echo statements to help debug.

Setting DE=kde doesn't work in my GIT setup. The reason is in GIT 
we changed the environment variables, but 3.5.13.x still uses KDE 
environment variables. Hence the partial success.

Other than submitting a patch for xdg-open to upstream I doubt 
there is little we can do.
