The HTB user guide (http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm)
says the following:

Note: The U32 classifier has an undocumented design bug which causes duplicate entries to be listed by "tc filter show" when you use U32 classifiers with different prio values.

What exactly is this bug? (I'm seeing its effects, i.e. the duplicates, and it's making my life a little difficult while trying to parse the tc output.)

If it is the bug i think it is - then it was fixed a long time ago; the doc you are referencing seemed to be dated.
Try a newer kernel if you are not and if it still persists, send the simplest setup you have that causes duplicates.
