QGIS 2.6.0 Atlas Export to multiple output files fails; is this a bug?

QGIS version 2.6.0, date 01/05/2014 OS Windows 7 Pro 64-bit

Description

When exporting Atlas features with Output to multiple files (i.e., 'Single file export when possible' checked OFF) and using either the Atlas export menu or the Atlas Preview export menu, Select Folder, the export then creates a single page file of the current atlas feature with the name of the Selected Folder and repeatedly overwrites this file as each atlas feature is exported. Reproduced for both pdf and images (jpg, png).

Steps to reproduce:

1. Create a set of features for Atlas generation


2. Export file name set to be based on one of the attribute fields


3. Select Folder


4. Export

Expected behavior: This feature worked fine for me in mid-November 2014, creating a folder of multiple output files of one page for each feature. i can report a bug if it appears to be one, but because it worked previously wanted to see if anyone had experienced this and resolved it.
