FBX exporter bin fails to export linked armature:
Traceback (most recent call last):
Exact steps for others to reproduce the error
Create a new file, delete all, add an armature, group it. Save it. Source.blend
Create a new file, link the previous group in it Link.blend
Export to fbx bin 7.4 => crash

@mont29, mind having a look? :)
Problem is with libs data, need to ref data by (name, lib) tuple instead of only name… Have to change this all over in the exporter I guess. :/
Ah no, cancel that, issue here is even more exotic - no need to link, it does not supports instances of groups containing an armature… TBH, I’m not sure I want to support that, will have a closer look though.
Will commit a 'fix' that will prevent that case from crashing on export. However, supporting dupli instances of armatures (as it is the case when instancing a group containing armatures) is simply not possible currently, and honestly I do not intend to do so in any near future (will put it on FBX TODO list though). Reasons are:
So in a nutshell: do not expect support of armature instances anytime soon.

Thanks for your concern.
FYI, the ASCII exporter support this, you could maybe try to copy it ?
No I cannot, 6.1 code and 7.4 one are totally different. Furthermore, I really doubt it’s working in 6.1 exporter either (at least not fully, might work in a few, simple cases), there’s even a comment in 6.1 ascii source code saying
# TODO - armatures dont work in dupligroups!
