OK, how about this (slightly less horrible than looking around
for files).

See if the current session manager is gnome (as opposed to KDE).
If it's gnome, execute "gnome-www-default-browser". KDE can do
something similar if it exists. Else fall back to the
wxLaunchDefaultBrowser route.

IE if we detect a session manager we know about, run a suitable
bit of code.

Code to check the session manager (Leio's) included below.

Does this sound a sensible aprroach?



Prints session managers vendorname (e.g, GnomeSM)
gcc -Wall -O2 -o smvendor smvendor.c -lX11 -lSM
#include <stdlib.h>
#include <stdio.h>
#include <X11/Xlib.h>
#include <X11/SM/SMlib.h>

main (int argc, char **argv)
       Display     *dpy;
       SmcConn     smc_conn;
       char        *vendor;
       char        *client_id_ret;
       dpy = XOpenDisplay(NULL);

       smc_conn = SmcOpenConnection(NULL, NULL,
                                    999, 999,
                                    0 /* mask */, NULL /* callbacks */,
                                    NULL, &client_id_ret, 0, NULL);

       vendor = SmcVendor(smc_conn);
       printf("Session manager vendor: %s\n", vendor);

       SmcCloseConnection(smc_conn, 0, NULL);

       return 0;
That sounds like a good idea, but the use of Smc* function will mean that an extra library will be needed.
