crash loading effect after using [EffectRack1_EffectUnitX], clear

[mevsme]

Ubuntu 16.04 x64
Mixxx 57be954cf5b1ee1d7bebdc6b5f44ed791424843d

How to reproduce:
1) Unload Filter from FX slot, make it empty
2) Load something into slot

PS: maybe I am deaf, but I still can not hear any effects even I have this settings:

Thank you for the report and the backtrace. Can you attach your ~/.mixxx/effects.xml file then try deleting it? When you encountered the crash, did you start Mixxx with a different skin then switch to Tango? If so, which skin were you using before?

Apparently we have a discoverability problem with the effect enable buttons in Tango. Click the name of the effect to enable it. The buttons below the parameters control the metaknob linkings.

> 1) Unload Filter from FX slot, make it empty

How did you do this? By selecting "None" in the drop down menu? Or did you use something on your controller mapped to [EffectRack1_EffectUnitX_EffectY], clear?

How was the Filter effect loaded? Was it restored from a previous time you ran Mixxx, or did you load it with the drop down menu in Tango?

The backtrace looks incomplete. If you can reproduce the issue, please run "set height 0" on the GDB prompt before "thread apply all bt".

Did you use something on your controller mapped to [EffectRack1_EffectUnitX],prev_chain or [EffectRack1_EffectUnitX],next_chain?

[mevsme (mevsme)]

Yes I have controller attached. And I have this lines in javascript file:

ｅｎｇｉｎｅ．ｓｅｔＶａｌｕｅ（"[ＥｆｆｅｃｔＲａｃｋ１_ＥｆｆｅｃｔＵｎｉｔ１]"，"ｅｎａｂｌｅｄ"， ０）；
ｅｎｇｉｎｅ．ｓｅｔＶａｌｕｅ（"[ＥｆｆｅｃｔＲａｃｋ１_ＥｆｆｅｃｔＵｎｉｔ２]"，"ｅｎａｂｌｅｄ"， ０）；
ｅｎｇｉｎｅ．ｓｅｔＶａｌｕｅ（"[ＥｆｆｅｃｔＲａｃｋ１_ＥｆｆｅｃｔＵｎｉｔ３]"，"ｅｎａｂｌｅｄ"， ０）；
ｅｎｇｉｎｅ．ｓｅｔＶａｌｕｅ（"[ＥｆｆｅｃｔＲａｃｋ１_ＥｆｆｅｃｔＵｎｉｔ４]"，"ｅｎａｂｌｅｄ"， ０）；

Here's the crash video: https://youtu.be/F-WBc0c486U

I'll try to do what you sad and investigate.

1) commenting .js lines - didn't help
2) delete effects.xml - didn't help

New data: After deleting effects.xml I had empty effect slot. I have just selected some effect, and it loaded. But than I pressed this https://pp.userapi.com/c836729/v836729332/3db95/tLAlVQFRb-g.jpg
Loaded another one and got crash.

I loaded into Tango skin.

Wrong image, this is right: https://pp.userapi.com/c836729/v836729332/3db9c/UyaIuvcxsyA.jpg

So, now I can select any effect, but if I press this button, next selecting will cause crash. As on the video.

[mevsme (mevsme)]

Hm, I have another crash not connected with effects. I have just loaded a track, got crash and made this backtrace. Will log file help?

[mevsme (mevsme)]

I believe my js\mapping for a controller crashed it, last lines from log file.

But now I can not reproduce it. And I run it without gbd.

Ah, okay. That button is connected to [EffectRack1_EffectUnitX], clear. I can reproduce the crash after pressing that. I'll look into it.

It looks like the new crash isn't related to your script. It started in WaveformWidgetRenderer::draw. If you can reproduce that, please open a new bug for that issue.
