I have a message I just received, which I have no trouble viewing, but as soon

write(2, "\n(balsa:19050): gtkhtml-CRITICAL"..., 98
(balsa:19050): gtkhtml-CRITICAL **: html_engine_unrealize: assertion
'HTML_IS_ENGINE (e)' failed
...
Balsa is compiled from git, gtk3 branch, with gtkmthm 4.10.0. I suppose I'll
reinstall webkit-gtk, but that's a long compile, and I'm leaving on vacation
tomorrow, so I doubt I can troubleshoot much before I get home. I was able to
manually edit the mbox file, and move the bad message to its own file, so I can
keep working.
The odd thing about the message is that it's rather short, with
Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: base64
and the unencoded content being essentially "<p>message about a successful bill
payment</p>" where the message is only one line, 118 characters, with no non-printable or
other strange characters.
I can try downgrading gtkhtml from 4.10.0 to 4.8.5 to see if it matters, but I just don't
understand why the crash is on leaving the message, not on displaying it. By the way,
"display source" works fine, and closing the source window is also OK. Not
sure what else I can try, in terms of debugging.
As always, thanks for any suggestions.

Well, it turns out this is not new. Google led me back to this mailing list in August, 2011. Ildar
reported the issue, and Peter's response was "Yes, I see the same thing. It seems to happen
when when clearing the display after showing an HTML message part to show something else, and it
seems to happen only for certain HTML parts, not all, but predictably for the vulnerable parts."
and suggested it was a gtkhtml4 bug. Well, I have a short example - where should I file it? Even if
the entire HTML snippet is <p>.....</p> which may not be legal html, it shouldn't just
crash. Unfortunately, I'm leaving for vacation tomorrow, so I don't have enough time to switch back
to webkit until I return.
I just configured Balsa with html-widget = gtkhtml4 for the first time in a
while. It just doesn't work well! Scrolling a message that needs scrolling made
the text disappear in a flash, and I had the same crash on selecting a non-html
message. We must be using the widget incorrectly, but I'm not sure how.
Has anyone had success with a gtkhtml4 build?
Peter
