Causes and Solutions
Cause 1 - Bow Reach Bug
This problem occurs when a bow being equipped has a reach of 0.
Solution #1: A number of mods address this problem, most notably, the Unofficial Oblivion Patch addresses this problem and many other bugs in the Vanilla game.
Solution #2: Wrye Bash's Bashed Patch contains a tweak that should correct this setting in all loaded plugins, not just Vanilla Oblivion's ESM.
Solution #3: There are smaller mods that specifically address this issue for Vanilla and SI as well: Bow Crash Fix by Quazzy for SI.
