ah, I didn't know that... but initialization of statics would only happens 
once, when a library is dynamically loaded, no?

some times ago we had a bug in the arena allocator, where if the last part was 
unloaded and KHTMLFactory destroyed, static variables remain, so next time a 
KHTMLPart was created, statics were not reinitialized.

This would explain (what looks like) invalid reads on the cache structure...

    void cleanup_thaibreaks()
    {
        delete cache;
+        cache = 0;
    }
