large file won't convert

greetings,

i am having trouble converting a large open office odt file with calibre. the file is text an is 17,314 KB. i have tried to convert to epub and mobi with no luck. the conversion takes several hours and at the end i am left with an error file.

can anyone sus out this file and make senses as to why calibre will not complete the converison?

i will post the error msg if it will illuminate the problem
