Did you try a mred built on a stock 7-STABLE? When it first stopped working (around the 11th, from memory), my first approach was to rebuild it (over and over, and attempt to debug it...) No joy that way. It's only since I reverted to the earlier version of FreeBSD that it's started working again. As part of the attempt to make mred work again, I re-built *all* of the ports that I have installed (some 900-odd), so all of the libraries in /usr/local/lib are post-15 Jan., and have whatever effect the change introduces. Perhaps that is why epiphany has gone unstable on me (seems to be complaining about failing to connect to gnomevfs). I suspect that mred wasn't minding false-positives before, because it's been configured/compiled with pthreads enabled (for the benefit of Mesa/OpenGL, apparently). If you think that it might help to track things down, I can jump forward to -STABLE again and rebuild at least all of mred's dependencies, but that's going to be a slow process... Reckon I'll give that a go. No point staying in the past, now that we know where abouts the breakage occurred. Am I right to assume that this is *not* i386? I have 7-PRERELEASE (i386) cvsup'ed on January 22, early morning EST, and mred built from vanilla 372 sources (per your earlier recommendation) on January 8th. They seem to be pretty happy with each other. If there is any information I can provide that will help you with your quest, please, let me know.

[patch] glib20, UTF-8 and string collation
I have seen recent commit WRT string collation in devel/glib20 by
marcus, so I have decided to check if there is an interest to fix SEGV
in g_utf8_collate when it is given 8-bit non-UTF-8 string(s) to collate.
Good (but by no means only) example of this would be using Evolution to
open mailbox with the mix of KOI-8, CP1251 and UTF-8 message subjects
and order them by the subject. Admittedly, I do not know whether there
are special symbols that trigger the situation or any mix would do. vova
at fbsd ru posted test case mailbox under the link below.
Full discussion including my first approach to fix this problem could be
found here
http://bugzilla.gnome.org/show_bug.cgi?id=492389
Slightly different approach is attached to this E-mail.
Without either patch, my Evolution will core dump on start-up.
First patch was rejected by gnome folks with the recommendation Don't
do that, which, unfortunately, is not that easy to follow ;)
Any comments from people with the knowledge of gnome, UTF-8 and string
collation will be greatly appreciated.
I am not subscribed to ports@, please, make sure to keep me on CC list
when replying.

I'm not sure why the malloc and copy. Why not just use g_strdup()?
Because I don't know much of anything about glib programming, and I was
suspecting that someone will use g_free() on the result, so g_malloc()
sounded like the plausible candidate. I really hope someone with
the necessary knowledge will come up with the right solution, but, for
now, I do what I can.

I can't imagine you're alone in this. But then again, any Cyrillic mail

More importantly, it is UTF-8 spam -- in order to trigger this, you need
KOI8-R or CP1251, and in the sorted column to boot. I suspect that
Latin1 or ShiftJIS would do the trick too.

Alexandre,
The problem you exposed have its roots in Evo code. g_utf8_* stuff
defined to work on *utf-8* strings only and have undefined behaviour on
MBCS strings. It may sound stupid but crashes are allowed in this case
:-) Even we apply your latest patch the true problem solution will be
only postponed. We have to continue with Evo source. Find subject parser
part and ensure that it will be utf-8 encoded string at the end.
rant
While I see this as the noble goal, I fail to understand why asserts are
OK 10 lines above my latest patch, but not in this specific place. Nor
does this latest patch mask any issues in Evo -- you still get
Glib-CRITICAL assert. Hell, you even get assert without the patch if
your CHARSET is ASCII, but core dump if your CHARSET is xx_YY.UTF-8. If
we are talking noble goals here, how about some consistency in the error
handling?
/rant
On the more productive note: I have picked up more glib programming
today than I had before (or cared to) -- it's easy to improve when you
started from the veritable zero ;) However, it might not be sufficient
to do what needs to be done to Evolution. One thing you can help me
with, is to suggest glib function, I can feed arbitrary string of bytes
(either counted or zero-terminated) and it will tell me whether this is
valid UTF-8. g_print() apparently does this somehow, so there must be a
way.
As promised, I'll crawl back under my rock and wait for rainy weekend to
read some Evolution code.
All the best,
Alexander.
BTW: What happened to no top posting rule?
