Please attach the file.

Is there any change you can update to libepub 0.2.2?

Comment 3 buffyanam 2014-01-25 16:01:05 UTC

It seems it's libepub's problem: when I tried libepub 0.2.2, replaced the old libepub with the new one, then did the above procedure, okular just warned me  it can't open the file, not crash.
