Hello!

I am having an issue with Pan, where it is crashing when I try to open certain
articles.

All spam reports received get posted to a newsgroup, as-is.  It seems that, in
certain cases, opening those posts causes Pan to crash.  The particular article
causing the crash has multiple multipart MIME layers:

* The article's content-type is multipart/mixed, which contains a single message/rfc822 email.
* That email's MIME type is also multipart/mixed, and contains a single multipart/alternative.
* The multipart/alternative contains two items: A text/plain and a third
multipart/mixed.
* The text/plain is an email as plain (quoted-printable) text.
* The innermost multipart/mixed contains a text/html part (the email as HTML)
and a PDF (as an inline attachment).

I think something about that post, and all of its MIME layers, is crashing Pan.

I am attaching two items.  First is the post in question that is crashing Pan.
Second is the output of running `gdb --args pan --debug`, showing Pan's debug
messages and the crash backtrace.

Let me know if you need anything else!

Hello Karl
certain

In 2015, you reported a bug on Pan which crashed when opening some articles.

The backtrace shows a problem with g_mime_multipart_encrypted_decrypt (). I
guess that the crash was triggered by utf-8 encoded character that can be
found in the article mentioned in the bug report [1].

A lot of related to utf-8 and gmime are now fixed in Pan which is now v.0150.

Could you try again ?

If not, if the leland group public ? We hope to be able to reproduce this bug.

All the best

close 779364 0.150-1
thanks

Since I can't reproduce this problem and I got no news for 3 weeks on
Debian side, I'm going to closes this bug.

Feel free to re-open if you still have problems.

All the best
