[sylpheed:37157] eMail causes crash of sylpheed

[Joachim Selinger]

Hello Hiroyuki,

after many, many years without any bug or crash of sylpheed, today it happened.

When clicking on one specific mail, sylpheed hangs in the air forever and
does not respond anymore. Only a kill -15 stops it. As I did not want to send this
mail (from an ad mailing list I subscribe to) to the list, I have the link to
it here:

https://www.jocki.org/tmp/bad-mail.txt

An strace on sylpheed showed the following:

...
access("/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf", R_OK) = 0
poll([{fd=3, events=POLLIN|POLLPRI}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 3, 0) = 0 (Timeout)
recvmsg(4, {msg_namelen=0}, 0)          = -1 EAGAIN (Resource temporarily unavailable)
recvmsg(4, {msg_namelen=0}, 0)          = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=3, events=POLLIN|POLLPRI}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 3, 0) = 0 (Timeout)
...
so far it was ok, then i clicked the mail in question just here

Any chance you can pinpoint the issue? I run debian 11 and the version of sylpheed
that I am using to send this mail. 3.7.0

If you need any further data, let me know how to get it (I am not really a good
programmer, but I can use the command line for anything that I am told ;-) )
