I don't know about other news-clients, but while I was investigating the 
problem, I saw a reply posted to this group (group for me, since I get it 
thru gmane, tho natively it's a list, thus...) from I think it was kmail, 
that had exactly the same symptoms.

I switched from kmail to claws-mail due to bugs when kmail akonadified, 
so I don't have immediate kmail dependency info as easily available to 
check as I would have some years ago, but given the exact same symptoms 
and the fact that the mail came from someone complaining about the 
problem on pan at the time, I'm as sure as I can be without actually 
checking dependencies that kmail is using gmime and is affected as well.

I'd have guessed claws-mail was using gmime as well, but a depgraph here 
didn't turn it up, down to four levels below claws-mail itself.   (Based 
on past experience with these queries, go too deep and pretty much every 
library and system app in the system is brought in with some gentoo-
optional USE flag or another, and 2-3 levels deep tends to be a practical 
limit on significance, and I went a level beyond that, so...)

Meanwhile, querying the other direction, what depends on gmime, returns 
only pan, here, so at least on my gentoo system, with my policy of 
turning all USE flags off by default even if they're on in the profile, 
and limiting packages to only what I need (gentoo definitely rewards the 
good security practice of only installing what you're actually going to 
use, because every installed package will have updates, and on gentoo 
that means building them, so there's a higher cost to keeping unnecessary 
packages installed on gentoo than on binary distros), dependencies on 
gmime really /are/ less than I'd have expected, only pan.  As I said, I'd 
have expected at /least/ claws-mail to use it, but apparently not... 
<shrug>

Which makes me feel a bit better about masking the newer gmime versions 
and copying the old gmime 2.6.15 ebuild to a local overlay since it's no 
longer in the tree (tho 2.6.13 is, but I didn't want to go back farther 
than necessary), since only pan's using it, and I know I really do need 
it for pan due to this bug.

... Which I /still/ haven't actually filed.  I've been working more hours 
lately, which my wallet definitely appreciates, but those hours do have 
to come from somewhere, and my todo list is unfortunately one "where" 
that got cut, so...

But I'm supposed to have tomorrow (hmm... "today" by the time I post 
this) off, so your post bringing this up again might have come at the 
right moment. =:^)
