Title: Media Center 21.0.85 core dumps under Ubuntu 16.04
Post by: Boerd on May 31, 2016, 11:37:38 pm
The longest I had MC 21 running was for 3 days. Invariably at some point it doesn't start - it core dumps. I am left with 7 license restores after 1 week.
Every few days I have to remove the .jriver dir, restore the license and re-import the music. Any ideas?

What happens if you try to start mediacenter21 from the Terminal when it refuses to start? What does it say?

Don't worry about the restores, an admin can reset them for you if you run out.

Restarting shouldn't require a license restore.

Boerd is deleting the ~/.jriver folder, which resets the license and MC's settings.

My guess is MC's segfaulting on start - just need to see if any information can be gathered from it.

Looks like it's crashing on start in X. Sounds like a library incompatibility.

I saved the .jriver dir after reinstalling the license and imported my music and every time the MC 21 gets into a state where it crashes I restored the .jriver
Now I am not convinced this is solving the problem - I see random crashes then I can restart (or not).
I am running KDE on ubuntu 16.04

It says core dumped :)
Good to know I will not run out of restores - I didn't know that. Thank you!

It might also be dying on a bad file.
You could turn off auto-import and thumbnailing and see if that changes anything.

I'm was also getting segmentation fault core dumped when trying to run on 16.04 Ubuntu.

I fixed it by DLing .85 from the top thread, then running sudo dpkg -i on it. It gave some dependency issues (libpango or something or other), so I ran sudo apt-get -f install, which installed it and now it runs, but I cannot connect to servers...

Are you using auto-import?

No, not on the client machine. I only connect to the server from that machine, not run a local library at all.

It's all good now. I restarted MC on both machines and am good.

My suggestion to the OP is to run a manual update to ensure libpango* is installed, as it seems it wasn't by default.
