Here's a sample video I found that I assume is OK to share a link to.
Just open it, turn subtitles off, and finally open the same file in the
same Totem window.

Thanks, it looks like it's neither new nor a regression then (in the
sense of something that used to work and stopped). Ideally having an
example would make easier to test/work on the issue but I guess most of
subtitled videos are non free content and can't be easily shared here?

2019-05-02 Thread mattiasje
Yes Sebastien, a .crash file appears in /var/crash/ if I killall -ABRT
totem.

However, as there's so much talk of crashing, I want to stress that the
entire program has not crashed. It still listens, and obeys, a click on
the close button. I just noticed that you can even navigate the UI and
even load a new (not subtitled) file and it'll play.

The issue comes from playing one subtitled video, trying to load a new
(or the same) subtitled video, and the video portion of the UI getting
stuck and the video not playing.

In previous versions of Ubuntu, trying this meant a full crash. Clicking
the close button led to a wait for the force quit option. But now in
19.04, the program is alive. It just can't play the video. It's not an
issue of the video being paused either, clicking the play/pause button
does nothing and the seek bar can't be interacted with.

the backtrace is not really that useful since it lacks debug symbols

Did you get any file in /var/crash following Daniel's recommendations?

Hopefully I'm adding the attachment correctly, and hopefully it contains
some useful information.

I was unable to follow the instructions exactly as gdb would hang when
pressing ctrl+c. I waited at least ten minutes but the prompt wouldn't
appear. I had to kill totem outside of gdb to progress to where I could
type in the backtrace command. Further, while the wiki suggests sudo
should only be necessary for programs run with sudo, I was unable to
attach the totem process without it. So that's what I did.

Could you add a video example to the bug maybe?

Those reports don't have useful stacktrace, could you try to get one
following the steps on
https://wiki.ubuntu.com/Backtrace#Already_running_programs

Note that the journal one one of those include totem warnings

'gst_caps_get_size: assertion 'GST_IS_CAPS (caps)' failed
gst_mini_object_unref: assertion 'mini_object != NULL' failed
gst_pad_set_caps: assertion 'caps != NULL && gst_caps_is_fixed (caps)' failed'

That's certainly one totem crash, thanks :)

Unfortunately that one doesn't seem to be readable/retraceable. So
please try repeating with more freezes and forced crashes.

2019-05-01 Thread mattiasje
I used ubuntu-bug as per instructions. The first time ubuntu-bug crashed
when I hit the Send button, upon a second attempt it might have been
successful, but I'm not sure. The ubuntu-bug window closed immediately
when I hit Send, without feedback from either from the ubuntu-bug UI or
in the terminal. I'm not sure if the information can find its way to
this particular bug report given that I was never asked to specify where
it belongs. This is all rather confusing.

Upon further testing of Totem, I have discovered that what's triggering
the issue is the subtitles being turned off. Simply open a file, turn
the subtitles off, and try to load a new file. No need to wait.

When totem is frozen please open a terminal and run:

  killall -ABRT totem

Now wait a while for a crash report to be written to disk. The totem
window should vanish when it's done. Next, send the resulting crash
report per these instructions:
