Gimp-help not working after portupgrade

[Mike Clarke]

As a follow-up to my last post I've discovered something very odd.

If I run gimp from a terminal window using just the command gimp then I 
can access the local help files with no problem (but still can't load 
any files via http).

If I run gimp from the KDE menu (or by pressing ALT+F2 and typing gimp 
into the run dialog then I get the "The GIMP user manual is not 
installed" error as before.

I've tried to "run truss -p" on the process started from the KDE menu 
but truss aborts with a message "Cannot malloc -33677376 bytes for 
pollfd array: Cannot allocate memory" - yes thats a minus sign in front 
of 33677376).

Any suggestions where I go from here?
