some applet sigsegv

[Xun Cheng <xun cs ucsb edu>]

I built gnome v0.20 on my linux box (glibc)
and am running it under fvwm.
Everything seems fine except that I can't add
some applets (like fish, clock and mail check) 
to panel. When I add those
applets, it appears for a while and then disappears with
the following error message:

started applet, pid: 17042
Saving to [/panel/]
Saving session: 1
** ERROR **: sigsegv caught
invocation(11) aborted

** WARNING **: Error on sending 'session save' to applet!

Could anyone give me some idea on what is the possible
reason or how I can find(trace) it to the right module.

BTW, I can add cd player, cpumemusage, but can't add fish,
bussign, clock and mail check, modem light, print applet.

Following is the output of ldd fish_applet:
