Dear Maintainer,

I cannot get thunderbird to start on a fairly newly instaled debian testing 
laptop.

On a newly booted computer:

rene $ killall -1 thunderbird
thunderbird: no process found
rene $ killall -1 icedove
icedove: no process found
rene $ rm -r .thunderbird
rene $ thunderbird

just gives me a dialog with the message:

"Thunderbird is already running, but is not responding. To open a new window, you 
must first close the existing Thunderbird process, or restart your system."

I have tried using an old profile, a new profile, safe mode, removing 
.thunderbird and .icedove totally, ... to no avail.

Thunderbird won't start.  I have no idea what to do next, and google doesn't 
help much.

Starting Thunderbird with the option '--debug' gives at least some more
information if something is already going wrong before Thunderbird will
be called itself.


No information printed, except:

nuno@host:~$ thunderbird --debug
[calBackendLoader] Using Thunderbird's builtin libical backend
Warning: unrecognized command line flag -debug

I have tried packages from stable, testing and experimental, all the same.

-- System Information:
...
Versions of packages thunderbird suggests:
ii  apparmor          2.11.1-3
pn  fonts-lyx         <none>
ii  libgssapi-krb5-2  1.15.2-2

You have installed apparmor. Have you tried to disable the AppArmor
profile for Thunderbird and check for the further existence of the issue?

 $ sudo aa-disable /etc/apparmor.d/usr.bin.thunderbird

That does the trick.. Thunderbird now starts ok.

Also I suspect then some messages about denied access by apparmor.

 $ sudo journalctl -kaf --no-hostname | grep -w 'apparmor="DENIED"'

No output here. Thanks,

Nuno.
