#1 crash for daily 91 and 92

clochrua, thanks for the report. Can you provide a sample message, using "Attach new file"? If not, does this happen for all messages, or just ones that have some characteristic, such as an attachment?

Wayne, just tried to print on the bugzilla e-mail from your comment 2 and same crash. Followed your advice, will "attach new file" in next comment and below is the stack trace:

When this started 5 days ago then it will be handled in bug 1714639. See also our port bug 1719625.

Hello,
re comment 4, I will enter my findings against bug 1714639
Bill

Probably dupe of bug 1714639.

This isn't showing up as a topcrash for 91 https://crash-stats.mozilla.org/topcrashers/?product=Thunderbird&version=91.0. In fact it doesn't show up at all - which can't be right

Print doesn't get very far in 91 - stuck in Preparing Preview. bug 1720713

I also have a crash in daily when trying to print one mail message. Gene Smith pointed me to this bug report. My dumps:

After the first dump at 08:31, I duplicated the problem at 08:36. I normally do not print mail messages, and I have not tried to print any others.
