Hi KevinH,

Unfortunately, changing

if hordt2 is not None:

to

if hordt2 is not None and len(text) > 0:

didn't have the desired effect. The French dictionary still failed to unpack, but this time Kindleunpack displayed a longer error message:

Spoiler:

Error: Unpacking Failed

(I've got similar longer messages for many of my other test files.)

I've created a small German-English proof-of-concept test dictionary based on the latest recommendations from the Kindle Publishing Guidelines for you that I compiled with both Mobigen and Kindlegen without error messages. Hopefully, this will make it easier for you to reverse-engineer the binary files, since you have access to the actual source files.
The .zip file contains the source files and 3 binaries each generated without compression (c0), with standard compression (c1) and maximum compression (c2).

BTW, I believe one reason why the Swedish dictionary decompiled fine, is because I used a redundant inflection syntax:

I used for example:

<idx:entry>
	<b><idx:orth>positiv
	<idx:infl><idx:iform value="positivs"/></idx:infl>
	<idx:infl><idx:iform value="positivet"/></idx:infl>
	<idx:infl><idx:iform value="positivets"/></idx:infl>
	<idx:infl><idx:iform value="positiven"/></idx:infl>
	<idx:infl><idx:iform value="positivens"/></idx:infl>
	<idx:infl><idx:iform value="positiv-"/></idx:infl>
	</idx:orth> </b> 
	<i>subst</i> <br/>
	absolute
</idx:entry>

instead of the syntax recommended in the guidelines:

<idx:entry>
	<b><idx:orth>positiv
	<idx:infl>
		<idx:iform value="positivs"/>
		<idx:iform value="positivet"/>
		<idx:iform value="positivets"/>
		<idx:iform value="positiven"/>
		<idx:iform value="positivens"/>
		<idx:iform value="positiv-"/>
	</idx:infl>
	</idx:orth> </b> 
	<i>subst</i> <br/>
	absolute
</idx:entry>
