I just tried to split a combination Mobi/KF8 and the KindleUnpack plugin tossed up the following error...
Code:
calibre, version 2.14.0
ERROR: KindleUnpack - The Plugin v0.77.0: mobi_split instance has no attribute 'result_file7'
Traceback (most recent call last):
File "calibre_plugins.kindleunpack_plugin.extraction", line 218, in combo_split
File "calibre_plugins.kindleunpack_plugin.utilities", line 297, in writeSplitCombo
File "calibre_plugins.kindleunpack_plugin.core.mobi_split", line 429, in getResult7
AttributeError: mobi_split instance has no attribute 'result_file7'
The standalone KindleUnpack 0.77 worked fine to split this file.
