Various single files, which seem to be FLACs only will crash MBz Picard

Tags: #<Tag:0x00007f4d5bf414d8>

Yesterday I was able to load my entire library(33,000 tracks) and clustered them as well, but I found out I would never finish the album data loads, and abandoned it.
Today I broke it down into smaller sections and now upon adding a folder it will load a few hundred unclustered files then crash. I isolated it all the way down to one single file. Only to realize that it seems to be a problem per every 5-10 albums.

What could have happened since yesterday when it loaded it all up no problem?

  • Which version of Picard do you use? 2.3.2
  • Which operating system do you use? Win 10 64bit
  • What did you do when the bug occurred? Added single file
  • What actually happened and what did you expect to happen? It loads in, then after a few seconds MBz simply closes itself.
  • If you’re using plugins, which plugins do you have enabled? I disabled wikidata genre and disabled

This is the debug report.

For actually debugging this I’d need the file to test. But does the crash actually happen when you load just this single file, or only if you load several files at once?

Hey I responded to your email.

Thanks. I tried with your files, but could not reproduce any issue. Could you share your scripts, maybe it is related to this.

Can you reliable reproduce these crashes with these files or does it happen only sometimes?

I’m not aware of running any scripts. It’s simply a clean install.
So it’s working a bit differently today and it seems like two files together are the problem.

I will follow up with files at your email again.

I’ve had the same issue recently. At first I though it was a couple of specific folders, but after reading this, I experimented. I can load each of the 11 files in individually, but if I add a second file from the same group, Picard closes immediately.

I will follow up as I discover new informaiton.

I tested after trying each of these things. Updated all plugins, disabled plugins, reset all defaults. Picard crashes on load, with automatically scan disabled.

What I first found gets me past is;
If I have a completed album in the right pane, and add each of the files one at a time, it will scan and tag them all. If at any time, Picard is processing more than one of the suspect files at a time, Picard will exit. After this, the files will scan with no problems, suggesting that the tag frames are the problem.

I was able to fix the issue altogther by deleting the tags from the files in question using MP3Tag.


I should have some time to test that out when I get home. I’ll report back.

EDIT: Actually. I’m going to try my other method first, which will be bringing the files into work for another computer to take a shot at it. Hitting offending albums with mp3tag first will be a lot of time investment I’d rather skip.

Things are going smoothly on my work computer. I wish I could say why.

Some late feedback, but I have finally found the fix for the issue Thanks for providing the broken files.

So the basic issue is that the tags contained some null characters, and that caused a crash in Picard column sorting code. That’s also the reason why it worked for you both after you removed or resavedthe tags of the files, as this fixed the files.

Bugfix for this is in review, see . Should be fixed in the next release. Thanks again for reporting.
