It's something to do with the pool-allocation.  valgrind is probably showing
me the problem that I'm looking for, e.g., this (repeated a lot of times):

==6270== Invalid read of size 1
==6270==    at 0x805C0EC: display_line (./GridText.c:1282)
==6270==    by 0x805D446: display_page (./GridText.c:2001)
==6270==    by 0x8069BF2: HText_pageDisplay (./GridText.c:6820)
==6270==    by 0x808656E: mainloop (./LYMainLoop.c:6241)
==6270==    by 0x807A28A: main (./LYMain.c:2060)
==6270==    by 0x402A6577: (within /lib/libc-2.1.3.so)
==6270==    Address 0x4331E80E is 18 bytes inside a block of size 32776 free'd

==6270==    by 0x805BFE7: HText_free (./GridText.c:1177)
==6270==    by 0x806BD94: HTuncache_current_document (./GridText.c:8112)
==6270==    by 0x807DCBD: handle_LYK_ACTIVATE (./LYMainLoop.c:1427)
==6270==    by 0x8087DBE: mainloop (./LYMainLoop.c:7113)
==6270==    by 0x807A28A: main (./LYMain.c:2060)
==6270== 

The problem happens with/without color-style.  Since it's probably a memory
issue, it's not necessarily going to break the same way for everyone.
