(gdb) quit

platform is arch linux I have both qt4 and 5 dev libs on my system and have built mixxx many times with both. I did scons -c and rebuilt with scons -j4 optimize=native and it builds and runs fine. the mixxx log is empty when it crashes

What signal did it crash with? (Right before the gdb prompt)

I had to rebuild again with qt5=1 to see it:

It is a crash caused by old vamp plugIns build with Qt4
Probably basically the same issue

my /usr/local/lib/mixxx/plugins/vamp/libmixxxminimal.so on Linux does not depend on Qt
Your one does without a doubt, looking at the backtrack.

I think your crash will be gone if you rename your /usr/local/lib/mixxx/plugins/vamp and
/usr/lib/mixxx/plugins/vamp folder, right?

Does anyone know when we have fixed this?
Normally the old libmixxxminimal.so should be overwritten by every normal install. Do we need to worry about it?
