It seems that conversion to .aac occurs in 2 steps; a 1kb placeholder .aac file is created, with the real information being contained in a .tmp file. Upon completion, the .tmp file is deleted and the .aac file becomes valid.
Unfortunately, some of the time it seems that the second stage is not carried out; the aac file obviously won't play, and renaming the tmp file doesn't work either.
