Conversion does not seem to work with any combination of files

[TheSpanishInq.]

Until a few monts ago I used win7 and conversion by Calibre worked fine for me. Since I started to use Linux (Ubuntu 12.10 64 bit) and Calibre for Linux it stopped working. I even tried a Win version with Wine: same result.
Am I doing something wrong? Are there too many options Checked? Help please.
Here are 2 error messages and the debug files as a ZIP attachment:

Turn off font subsetting, though I have to say that error you post should not be happening, and I cannot reproduce it.

[TheSpanishInq.]

Thanks for the quick reply. I did what you suggested. PDFto Epub seems to work now, batch conversion is still going on and after no. 15 from 147 still no errors. LIT to Epub failed, see report.
