Bug#916595: vlc: program doesn't close its process in some cases

[Bernhard Übelacker <bernhardu@mailbox.org>]

Hello
when you find such a failing to close vlc, you might
consider to run following line.
That should give you a vlc_*.txt file which contains
all threads current backtrace and might point to where
the vlc process is waiting.

for pid in `pgrep vlc`; do gdb -q --pid $pid -ex "set pagination off" -ex "set width 0" -ex "thread apply all bt full" -ex "info share" -ex detach -ex quit; done 2>&1 | tee -a vlc_$(date +%Y-%m-%d_%H-%M-%S).txt

Even better if debug symbols are installed like described in [1].
Starting with vlc-bin-dbgsym.

Kind regards,
Bernhard
