As always: that depends on what you call easy... :-)
It would require a general understanding of the Knuth/TeX algorithm  
for line-breaking[*], and specifically, the way inline-blocks are  
implemented in FOP.
It may be a side-effect of a more general issue with inline-block  
content, since I know for a fact that FOP trunk also has trouble with  
tables if they appear as descendants of fo:inlines.

You will probably need to dive into the code in  
org.apache.fop.layoutmgr.inline.InlineLayoutManager, and debug this to  
get an understanding of what precisely happens there (or more to the  
point: what precisely does NOT happen). If you need assistance with  
setting up FOP in an IDE, we have step-by-step Wiki pages for  
Netbeans, Eclipse and IntelliJ [**]

If I were to have a go at this myself, I'd have to start by debugging  
both cases, with and without inlines, to see what the exact difference  
is between the two.

Finally, and perhaps most importantly: if you're serious about taking  
this on, I invite you to subscribe to fop-dev@, if you have not done  
so, and follow up there (as this off-topic for the user list).
Once you're there, and have specific questions, we'll be here to (try  
to) answer them.

Thanks for your interest in FOP!

HTH!
