It's not severe.

This looks very interesting. I have no idea why this is coming.

I'd recommend you to check that the fonts mentioned in ~/.gtkrc and
/etc/gtk/gtkrc are present. Also, if you use some non-"C" locale, you might
want to check the fonts mentioned in fontset in /etc/gtk/gtkrc.LANGNAME
exist. The quick way of checking whether those national fonts are the cause:
run the program with environemnt variable LANG and all LC_* unset (in bash:
"(unset LANG; gedit)"
Also, a hint would be to recompile gtk/gdk and software without debugging
support (i.e. not stripping executable, but an argument for 'configure'
script that will make type-checking and type-casting macros become trivial). I
think it will reduce size of the code by 10%.
PS: just curious: how much RAM is on device? How big the linux kernel is? X?
How much ROM linux + X + libs + X stuff + gtk take?
