Bug? Error when attempting to add PDF in 0.8.2

[SilentSeven]

I'm attempting to add a PDF to the library and am getting the following error.

calibre, version 0.8.2
ERROR: Unhandled exception: <b>WindowsError</b>:[Error 3] The system cannot find the path specified: u'c:\\users\\jeff\\appdata\\local\\temp\\calibre_0.8.2_tmp_wpjlcf\\calibre_0.8.2_oboi3y_rm_worker'

Is this me or the program? I could add PDFs without error prior to the new version.

Restart calibre and disable whatever software you have on your computer that is automatically deleting temp files for running programs!

A reboot of my Win7 system seems to have corrected the issue.

I did not have to suspend any packages.
