i have several rw2 photos. in preview i can see them all converted. but when i try to convert them with batch queue manage the process fails if i use more then 1 photo (usualy from 600 photos one converted successfuly. the others are 0 Byte big). i did try also tiff instead jpeg but it failed also.
exporting the photos with embedded preview extraction works fine.
Steps to Reproduce:
1. select more than one .rw2 photos
2. open batch queue manager
3. assign tool 'convert to jpeg'
error msg: failed to process item and a 0 Byte .jpg in the export folder
a correctly converted .jpg
5 sample photos can be found here:

Batch Queue Manager : add new option to turn on/off multi-core support. This option is now turn off by default due to some dysfunctions under Windows, until it will be hack and fixed.
Note that problem are not reproducible under OSX and Linux here. Options is implemnted for digiKam 3.3.0 release.

in version 3.3.0 the batch conversion works fine with and without the multicore support.
