Hey, can anybody give me an idea as to what might be causing this assertion?

Assertion failed: (cache->size >= g->size), function evict_glyph_entry_from_cache, file Fonts/CGFontCache.c, line 836.

It usually occurs after I've deleted a number of rows from my table view, but I can't find any info whatsoever on what is means or might be causing it.

Here's the stack if it helps:
