    Somehow this patch makes superkaramba crash when the maindata.xml file has a python_module tag. When reverting this patch superkaramba does not crash anymore.
    I think the file position pointer is being corrupted somehow because there is always a short read on the .py file and all text files are corrupted,
    even the ones that do not suffered short read.

During download and copying/extracting the RES memory size of process kstars did not exceed 60 MB. The download file size was 1450631611 (1.35 GiB), the extracted destination file size was 2173117930 (2.02 GiB).
