Comment # 6 on bug 1017610 from Richard Bos

Is the problem located in this function:
https://github.com/yast/yast-pkg-bindings/blob/master/src/Source_Create.cc


As the URL changes here according the log:

2017-01-04 06:10:22 <1> install(3179) [Pkg]
Source_Create.cc(createManagedSource):158 Original URL:
cd:///?devices=/dev/disk/by-id/usb-TSSTcorp_CDDVDW_SE-208AB_RL6X853-0:0,
product directory: .

Somewhere between line 159 - 199 the URL gets a null string...
