Works for me and I dont see an error in that log, it looks incomplete which indicates, that something interfered with/crashed the conversion process. If you are on windows 7 note that conversion to PDF may or may not work depending on the state of your graphics drivers, in such cases either update windows or downgrade calibre.
Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
