Bug#916179: roger-router: selecting Preferences makes the program hang

[Bernhard Übelacker <bernhardu@mailbox.org>]

Hello Marc Lehmann,
in that situation an strace is probably not that helpful.
Maybe you can provide a backtrace while the program is frozen.


You might use following in a different terminal:
(Basically attaches a debugger every 30 seconds, prints the backtrace and detaches.)

while true; do echo ---- $(date); cat /proc/$(pidof roger)/stack; gdb -q -ex bt -ex detach -ex quit --pid $(pidof roger); sleep 30s; done


Even better if debug symbols would be installed like described in [1].
At least roger-router-dbgsym, better for the shown shared objects in the
backtrace too (if available in stretch).

Kind regards,
Bernhard
