I can confirm threading issues with older gmime, tho the ones I saw and 
which Dave may be referencing were bad posting behavior, improper 
"folding" (RFC term, aka wrapping aka splitting) of the references 
header, breaking it so an affected post would generally appear in the 
right thread (the first few reference IDs were intact) but in the wrong 
place (later IDs were missing or parsed incorrectly due to bad folding/
wrapping/splitting of the header).  It was bad posting, breaking the RFCs 
so many standards compliant clients would get the threading wrong.

For reference, I'm currently running gmime-2.6.20 here, without issues 
that I'm aware of (tho actual installed version is gmime-2.6.20-r3, the
-r3 indicating three distro-specific version bumps, possibly including 
patches for other bugs but just as likely simply due to distro-specific 
issues such as changes in dependencies).

IIRC the breakage was earlier in the 2.6 series, with I believe 2.6.17 
and 2.6.18 broken (regression from 2.6.16 which was IIRC fine) and I 
/think/ the fix in 2.6.19.

The gmime-2.4 series was unaffected by that particular bug, but of course 
they may have had others.
