Hello Lars,
just a wild guess - is claws-mail doing these ldap queries
in parallel in different threads? This in combination with
the unsteady connection to the server could make two threads
operate on the same structures?
In that case following gdb output would show all
threads with their backtraces:
(gdb) thread apply all bt
Or with showing also the variables:
(gdb) thread apply all bt full
And how do you get the backtraces? Are you running
with a gdb attached to it permanently?
Then you could create a core when the crash happened with
(gdb) generate-core-file /home/someone/corefile
Otherwise you could have a look at a coredump collector
like systemd-coredump and its setting Storage=external.
With these files someone could examine them later
for some more details, if the matching package and dbgsyms
are installed.
Kind regards,
Bernhard
