 could you please specify the steps you took to delete the track

i cannot reproduce this crash, and indeed, cannot delete a track using a key.

Thanks for the reply. everything works, but when you delete a track it crashes, selecting it and pressing delete, or even right mouse button, cut (I tried to do workaround).

the bug comes out after all the updates of the distribution, as soon as installed, I only have a clean distribution. on 15.1 it is rare, on 15.2 it always happens without any solution. everything works, only ardor 6, and mixbus 6, in all variations, have this bug. it does not apply to 5 and any other software

Sorry, but this still isn't an explanation that I can follow.

Can you provide very precise steps that you take (every mouse button, every keyboard key) in order to cause this.

Open project, (new or older, not inportant), mouse left click on existent track (record one if not present), for select, canc/del key on keyboard.

Mouse Right click on the track,and "cut" generate same error.

No mode for deleting track (midi, audio, inported or taked)

1) what type of track, audio or MIDI?
2) the keyboard shortcut in your debug output does not and cannot delete tracks, so I am not clear what it is that you are deleting/cutting ....

reporter   ~0024197

Specifically in this output, audio file, and used a "del" only key on keyboard. Tomorrow if it is useful to you, I can try other cancellation actions that you tell me, and I put the debug (today's specific output refers to the "del" key) but I can put the cutting debug here so as to give you extra elements

Ps on ardour5 same action with keyboard, "del" key, correspond to delete track and not crash

For track, i refer to tracks or portion of tracks, on the timeline

paul

administrator   ~0024200

OK, "tracks or portions of tracks" is a reflects some important terminology problems.

"portions of tracks" are called "regions" in ardour (and protools; some other DAWS refer to them as "clips")

Deleting a track means deleting the actual track, not contents of the track ("portions of a track"). There is no way to do this with a keyboard shortcut.

So, you are describing deleting a region (which may be the only region in the track) ? And then having problems as a result (and immediately after) ?

joboschetti

2020-05-19 11:13

reporter   ~0024203

Yep, Sorry for incorrect terminology, i refer to region (any region, midi audio importer or taked)

I cannot replicate this error with the instructions given.

Could you get a backtrace from this crash?

Get debug-build (https://nightly.ardour.org/). Then launch Ardour from a terminal window:

Ardour6 --gdb
[...]
(gdb) run <press enter>

Now make ardour crash, that returns gdb's prompt, there:

(gdb)  thread apply all bt


and press enter a few times (output will be several pages long) and attach the backtrace here.

There are various Ardour and MIxbus users who don't have this issue. So perhaps there's something "special" about your system.. Maybe translations?
or maybe some preferences, custom key-binding issue? Moving ~/.config/ardour6 away and starting a new might help, have you tried that?

hi, yes I did all the tests. The problem seems to be related to Leap 15.2, I suspect both with the new desktop plasma, since by downgrading to 15.1 with updated plasma, it kept the problem. Clean installation of 15.1 has fixed. I had tried format several times, but I had never tried without plasma updated on 15.1. I would still pay attention to any problems with the new versions of desktop plasma.
