well, it's of course possible that internally something has changed that way you or the other reporters will see now a crash. > Safe mode makes no difference. O.k.

This is unlikely nevertheless if you did not have issues with AppArmor and the previous Thunderbird ESR version. > Sometimes I do get AppArmor messages about Thunderbird in "dmesg", but not > every time I start so I don't know if they're relevant.

For AppArmor it's mostly easy to see, Thunderbird is usable or not. For a more detailed answer the messages you have got would be needed. I guess these are not related to this bug report. > I wanted to try "thunderbird -g", as suggested by the man page, but I don't > have thunderbird-dbgsym installed, and it doesn't seem to be available for > amd64 in sid. It is, but you need to add an additional source to your sources.list. I added a hint into the output of 'thunderbird -help' right now, you are the first person who spotted this issue. > Even if it was, there doesn't seem to be any run-mozilla.sh script > with the new version of Thunderbird, though there is one in the old > version.

I changed this too within the starting wrapper and man page file. Will be fixed within the next upload. So, what di you need to do now? You need to add an extra line to your sources.list, pick the entry for unstable from here: https://wiki.debian.org/SourcesList#Debug_Symbol_Packages Next update the package list as usual by 'sudo apt update' and install the dbgsym for thunderbird. $ sudo apt install -t unstable thunderbird-dbgsym Next you need to call gdb manually as the wrapper script needs to modified first. $ gdb -ex run /usr/lib/thunderbird/thunderbird Please be patient, thew start of thunderbird take significantly longer as usual. If you don't want to start thunderbird directly remove the options '-ex run'. > Since I was out of any better ideas, I ran it through strace.

Yes, the line gdb is showing were thunderbird is crashing is the interesting part, I'm sure this will show us an upstream issue. I see a small possibility that gcc8 might be the root for this crash. But then I also expect we would see a lot more bug reports related to thunderbird crashes. If the other reporters could give a message if they also use POP would also interesting! Also if the redo the steps of Torbjörn and get the same output would good to knoe. As written earlier, if the issue can be reproduced it's mostly much easier to get it fixed. Your report is more informative than the previous ones and gives me more clear picture that the crashes are probably not related to AppArmor. Let's see what gdb is showing, after this especially your report will need to get reported upstream. Regards Carsten
