Package: thunderbird Version: 1:52.5.2-2 Severity: important Dear Maintainer,
Trying to start thunderbird fails silently. Starting from the console shows this: ExceptionHandler::GenerateDump cloned child 1829 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... Took me a while to figure out what was going on. I found some people mentionning Apparmor while searching the web and in /var/log/syslog, I found that: Jan 11 09:06:18 flare kernel: [60207.044643] audit: type=1400 audit(1515657978.983:138): apparmor="DENIED" operation="file_mmap" profile="thunderbird" name="/tmp/.glXWcTtR" pid=534 comm="thunderbird" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 Jan 11 09:06:18 flare kernel: [60207.044646] audit: type=1400 audit(1515657978.983:139): apparmor="DENIED" operation="file_mmap" profile="thunderbird" name="/tmp/.glXWcTtR" pid=534 comm="thunderbird" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 Jan 11 09:06:18 flare kernel: [60207.044657] audit: type=1400 audit(1515657978.983:140): apparmor="DENIED" operation="mkdir" profile="thunderbird" name="/home/nab.nv/" pid=534 comm="thunderbird" requested_mask="c" denied_mask="c" fsuid=1000 ouid=1000 Disabling the AppArmor profile for thunderbird fixed the bug: $ sudo aa-disable /etc/apparmor.d/usr.bin.thunderbird I don't really know about apparmor and didn't change any of it's configurations, I think it came with recommendation. Looking at various bugs, it seems like the profile shouldn't be active. I don't have the /etc/apparmor.d/disable/usr.bin.thunderbird mentioned in README.apparmor. I update regularly (couple of times a week), but don't restart to often, I usually put the machine to sleep. And don't restart thunderbird often either, in that case. So I don't know exaclty when the change that provoked this appeared. But I think I did restart since the last thunderbird updates (26 dec). And restarted yesterday, and the issue appeared. So it looks there is an issue with the apparmor profile and with the way the disabling and enabling of it happens. I have a fairly bif .thunderbird (about 8GB), maybe that also started it. Mentionning this because it seems to try to mmap something. Tell me if you need additional information or if there is something I should try.
