Short description of error
filter_items function is broken (all items should be visible):

import bpy

class MyItem(bpy.types.PropertyGroup):
    pass

class TEXT_UL_my_list(bpy.types.UIList):
    def filter_items(self, context, data, propname):
        return [self.bitflag_filter_item] * 3, []

class TEXT_PT_my_panel(bpy.types.Panel):
    bl_space_type = 'TEXT_EDITOR'
    bl_region_type = 'UI'
    bl_label = "My Panel"
    
    def draw(self, context):
        self.layout.template_list(
            "TEXT_UL_my_list", "",
            context.window_manager, "collection", 
            context.window_manager, "collection_index")

bpy.utils.register_module(__name__)

if not hasattr(bpy.types.WindowManager, "collection"):
    bpy.types.WindowManager.collection = \
        bpy.props.CollectionProperty(type=MyItem)
    bpy.types.WindowManager.collection_index = bpy.props.IntProperty()

    for i in range(0, 3):
        item = bpy.context.window_manager.collection.add()
        item.name="Item %d" % i

Exact steps for others to reproduce the error
Run the script in blender's text editor.

Can confirm this. Still broken on Arch Linux, currently Blender 2.77 6aeb1f7f.
If you leave the flt_flags return value empty, i.e. remove [self.bitflag_filter_item] * 3, or use a different factor, then it works. But yep since the flag value is the same its likely an issue with its interpretation.
